Can't find their send file immediately from the browser button? I don't think my dad's gonna be able to use it without that.

:). I guess your father can right click the files and folder get the link.

I think his point is that browsing to their website, it's not entirely obvious how to quickly share a file. When you initially go to sendoid.com, their link to share a file is the most prominent element on the page.

Having the native hook into context menus is great in the file system, but if your users can't even install the app, what's the point? Having a dead simple browser experience is easier for users because it's one less step to do what they want to do - share files.

Excellent service! I tried it and it's very simple and easy to use. I'm curious... how does one initiate a P2P transfer between two computers using just browser technology?

We built a reliable file transfer method on top of the peer-to-peer media streaming technology used by Chat-Roulette and its clones, RTMFP.

Wikipedia claims "RTMFP will not support file or document sharing.[citation needed]". Ha.

Well done, that's a great idea.

I dig Crate, but we don't really do the same thing. letscrate.com is an really awesomely designed and implemented cloud storage provider. Sendoid.com is an in browser file transfer method. I wouldn't consider us competitors (at most very indirectly) and think more than anything we complement products like Crate or DropBox.

Hmm... I see that it's implemented differently, but aren't they accomplishing the same user task? Fundamentally, they're both solutions to the "this file is too large to email" problem. Or am I missing something?

Can you merge the ideas of sendoid desktop client with a pinch of dropbox, so we can sync folders with other computers, other people's computers (multiple folders, multiple computers) without a central server?

i.e. sendoid, but semipermanent links and folders instead of files.

I wish it could work for me. I love the idea of sharing directly with PCs in our network. Our setup is that we are travelling with my wife and constantly sharing files , now we use dropbox for that, but that means outside connection that relies on slow wifi. if your tool worked - it would be genius

unfortunately, it doesn't and sharing between Windows 7 chrome browser -> Mac .. just getting Waiting for the peer.

I can't say more specifics about network topology as its a hotel wifi.

It forms an encrypted direct connection between the sender and the receiver. The data never touches anyone else's server and is encrypted the entire trip. Everyone feel free to run a tcpdump dump of the traffic if you want confirmation thats not from the guy who made the service.

Interesting. How do you punch through NATs and firewalls? If you're doing it with p2p proxies, how do you do authentication and avoid mitm attacks?

If Sendoid is completely relying on RTMFP then the core security technology would have to be coming from Adobe. Check out Matthew Kaufmann's two year old talk on the subject: http://tv.adobe.com/watch/max-2008-develop/future-of-communi... Or Tom Krcha's blog which contains a number of Flash P2P entries: http://www.flashrealtime.com/ RTMFP is pretty fascinating technology that originates with a couple of very smart guys that Adobe brought on board (Matthew Kaufman and Michael Thornburgh). I'm curious if the Sendoid team has a non-Flash solution for 'restricted' devices.

Missing from the article (and the linked summary of other sites that do this) is letscrate.com, which does it so well that I'm not even interested in looking at sendoid. It's dead easy, and my clients understand and remember the name after I say it once.

Thanks for the mention! A lazy link because I'll never miss a chance to shameless plug: http://letscrate.com/ Excited to check out Sendoid though.

Looks very good. Found a small bug - At the pricing page I see a logout link, though I am not even logged in.

Really? You wrote custom crypto for this? Or do you use an SSL connection? I wouldn't have thought to ask that. My original concern was: how do you assure someone like me that an attacker can't redirect files to other locations?

The protection against redirection is inherent in the underlying peer-to-peer media streaming technology we built on top of (RTMFP), as is the crypto. Going off your profile you seem to be a security researcher type. Would love to discuss things further with you offband. Feel free to email me directly, email is in my profile.

I don't believe that your email is there. I may take a whack at it later this week (we're launching a product and I'm pretty busy, but I do love me some custom crypto protocol.)
