At ~ $150, that is an expensive solution, IMHO.

Depends what you compare it against, I guess. Seemed like a bargain to me.

For a third of that price, you can get a box that's also got a built-in ethernet switch and two WiFi interfaces. You're paying a ton for software convenience.

Being able to pdfgrep through years of documents has been a massive time-saver for me. My ix500 paid for itself in time saved and then some.

Although, my setup is less than ideal since the ix500 does not play nicely with linux. I scan to a shared folder on my Linux Desktop from Windows 7 running in VirtualBox.

For example?

It's been funny to watch the various phy standards converge in feature-space (alas, not interop-space) over time. PCI got a packet architecture with addresses and routing and credit-based flow control, USB got a packet architecture with addresses and routing and credit-based flow control, SATA said "screw it, we'll just become PCI-e, because they have packets and routing and flow control," and thunderbolt basically i…

Ethernet's also got the fun problem of the length of the runs being hugely different than pcie. What I expect is some kind of optical interface because of that. Optical thunderbolt might be the way for that to happen.

I thought 40G/100G ethernet was already optical (and multiplexed, much like PCIe)?

EDIT: yep https://en.wikipedia.org/wiki/100_Gigabit_Ethernet

I'm pretty sure that the only obstacles against "ethernet as a truly universal bus" are either minor (someone's got to invest in making adapter interfaces) or of the "why bother" variety. Unfortunately the latter is a bit of a show stopper as far as I can tell :)

What, a Raspberry Pi (which for that price doesn't have ethernet, wifi or a case for that matter), and on which I'll have to wait 5 minutes before the OCR is done that my central server takes 10 seconds to do; and which requires Windows 10 which didn't even exist when I first got my setup 2-3 years ago?

yes on linux(usbnet) at least for a long while, not sure about usb3.x or windows support though. https://en.wikipedia.org/wiki/Ethernet_over_USB A quick google showed there are Gigabit NIC over USB3.0 on the market already(for a while): http://www.amazon.com/Network-Adapter-Anker-Ethernet-Support...

I don't want a USB NIC, though, I want just USB to USB with as little shit in between them as possible to be as cheap as possible. Maybe even allow straight DMA to DMA across the machines due to it being USB 3.x.

That's not IP

Just buy one of these: http://www.amazon.com/Silex-SX-DS-4000U2-Print-Server-800MHz... . Works awesome, lets you buy the cheap non-workgroup version of pretty much everything (printer, scanner, label printer, ...) and still hook it up to a central server. I have a Fujitsu ScanSnap ix500 hooked up this way, which scans directly to Dropbox. Put the scanner anywhere where it's convenient to access, put paper in it, pres…

I bought one of these: http://www.amazon.com/gp/product/B005GM1Q1O/?&tag=bcgpfeed-2...

It's dirt cheap ($10-20), easy to load linux on [1], and it can be a simple file server, it can run minidlna, google cloud print [2], all kinds of stuff.

800MHz is not a screamer, but most simple I/O tasks like A/V streaming and printing are a walk in the park.

Thunderbolt is much closer to the PCIe bridge/RDMA style interface you seek. Not as ubiquitous or cheap as USB, though.

Hmm I appreciate more work in this field, especially Windoze compatibility, but... as said in Star Wars: Clone Wars... "Fifty tried, fifty died". USBoIP is a minefield.

Off-topic: Where in "Star Wars: Clone Wars" is that quote said? I seem to remember Durge boasting something similar, but the only direct references DDG et al. report are from fan-fiction [0], [1], and your comment itself.

(Fanfics not reviewed for Work Safety, caveat lector.)

IP over Firewire and IP over Thunderbolt both explicitly use native DMA to accelerate it. USB only gained DMA in 3.0, and most devices that would greatly benefit from it, don't.
