No, that won't work. Nothing you do client-side will help. OnLive Client OnLive Servers Deus Ex instance in a VM. The enter key is filtered out on their servers. Unless you hack into their servers and change that, there is nothing you can do on the client-side. That's what makes you completely helpless.

Ah, my apologies, I thought the game was running locally. (This sort of assholeness on the part of servers is basically why 'cloud computing' is such a bad idea.)

I disagree that cloud computing is a bad idea because of this. It has advantages and disadvantages. Not being able to hack around to make changes you wish is a disadvantage, but having access to something you would not have otherwise is a much bigger advantage.

i suppose you could try adding something to do the networking part via webrtc as the channel?

Nothing in the web platform lets you use raw (or TCP/UDP/etc) sockets. At most you could do VPN-style networking and use a bridge to talk to the rest of the internet; that bridge needs someone to host it.

damn. at least i found http://www.w3.org/TR/webrtc/#peer-to-peer-data-api which looks like its a standard to allow for peer to peer data transfer.

I'm presently working on networking (OpenCores ethmac) support for the jor1k[1] OpenRisc emulator. The plan is to push ethernet frames out over a web socket, and pipe them into a tun interface on the server via a node/python/C/whatever backend. From there, do whatever you want using your OS' standard networking tools (if you have specific needs for the server-side of this which go beyond using your os' standard tools…

I am really looking forward. If you have any wishes for an image with some tools, please let me know. Lynx, elinks, dillo, ssh, netcat, telnet ... whatever you want. Then I have to think about a demo. Maybe we can allow very limited access to some websites.

I think the biggest thing I'm overlooking right now is randomized MAC generation. I need to take a look at whether or not the ethoc driver will attempt to read the MAC from hardware before loading its own. If so, I can randomize MACs in my ethmac.js, or even make a backend service assign them to guarantee uniqueness.

Otherwise I think it'd be great to get an image together with all of those tools, especially Lynx. It'd be great if I could make the HN submission to the demo page via the emulator itself. However for now if I can get an ICMP echo I'll be happy.

I think when it's ready I'm going to set up a full-access reCaptcha-protected demo on DigitalOcean or AWS and see what happens. If people don't abuse it and if the bill isn't too bad, I'll leave it up. If not, I'll worry about how to do a restricted demo. It would be nice to get a network-friendly game in there, though.

Another great demo that we'd have difficulty with is browser-in-browser. Chrome-in-chrome, firefox-in-firefox. That would, however, be the ultimate sandbox.

Anyway, get in touch with me via e-mail or better yet, Skype (see profile). We can coordinate better there.
