I found this article http://ubuntuforums.org/archive/index.php/t-368869.html
Looking around the configuration files I didn't see any compression
enabled in /var/lib/tftpboot/ltsp/i386/lts.conf so I added:
## SSH compression between LTSP client and server
NETWORK_COMPRESSION = True
Subjectively, using Firefox and LibreOffice apps feels a LOT faster.
But with 11 thin clients working (4 of them using TuxType and 1 using
TuxPaint, the rest on Firefox or something else) the Dual Core was
showing 2.8 to 3.4 workload (too high!) and the network throughput was
still a solid 1.2GB per minute.
I know Tux-'x' is responsible for that, mostly, and is so slow it's
unusable with more than 2 people using it at a time). But do give
compression a try. I think it makes a noticeable improvement for
browsing and general work.
(Aside: does anyone know of a decent touch-typing program that isn't
as bandwidth intensive as Tux?)
And I must say, though I haven't tested exhaustively, while Firefox,
LibreOffice Write and Calc still take a fairly long time to load
initially; once they're running they seem fine. And then again, they
only take about as long as OpenOffice takes to start on a normal PC. ;)
Overall, I'm very disappointed with the performance of Edubuntu
compared to, for e.g., MS Terminal Server. One of these days I'd like
to get around to booting a PXE basic X client and running an
xtightvncviewer session to the host.

Not sure I understand the question.
From a terminal:
sudo adduser arbusername
Or use [System] [Administration] [Users and Groups] on the Gnome
(Under Unity you can just click on the [+] application launcher and
start typing user... or find it under System Administration.)

Not sure what you mean, again. In 11.04, which I'm using, the closest
thing I can imagine is iTalc.
HTH. And please try the compression and give us some feedback...
