Well, I did a bit more googling, and found an interesting and promising
project. This could possibly clean up a LOT of local device issues with
LTSP and give it some leverage few other terminal server solutions have!
Linux USB/IP project:
http://usbip.naist.jp/
This open source project provides a client-side "virtual usb host adapter"
and on the server side shares all USB events to the client. Thus, if the
thin clients have the server installed on them, all their events are made
available to the client (term server). The difficulty I still see is how to
sort out what usb events belong to what sessions, and more importantly,
making sure that they only show up to / are usable from that session.
Thoughts?

Hi all:
So, my boss just went and sold to his bosses the idea of using LTSP in our
Electrical Engineering coding lab. This is a good thing, except a firm
requirement for all these systems is that the users must be able to plug in
their EE boards (Xilinx/Digilent FPGAs) into the systems USB port to program
it. Xilinx provides a (poor) driver; there's also rumors of a linux open
source driver. However, I'm conserned about how to make it work. The
software doing the programming is binary (so I can't re-compile it), and
from what I understand, is fairly heavyweight. In any case, using that as a
"local app" would simply turn these machines into thick clients, as 90% of
what they're used for is this app, and probably 98% of the non-os cpu power
goes to this app.
So...Is there some way to generically forward a USB port to the terminal?
How about access raw devices?
I suspect the answer is no, and my boss promised the impossible without
talking to me first, but....It would be REALLY cool if it works!
