[SunHELP] X Windows bandwidth Utilisation

The bandwidth isn't all that great, the problem is latency. An X session can
require almost every packet to be acknowledged (this is highly application
dependent). We saw a (supposed) client-server application response time suffer
by more than an order of magnitude when deployed over a WAN connection vs a LAN
environment. The T1 showed only about 5% bandwidth utilisation max - the
problem was that the latency went from <10ms to >100ms due to the WAN
connection. There was an "animated" device on the application screen that some
idiot programmer had set to refresh every 1/10th of a second, and that one thing
just killed the throughput. Oops.
We've had better success, where the application suite isn't highly controlled,
by using products such as Citrix or the VNC suite for remote access.

Does anyone have any stats on XWindows bandwidth Utilisation ?, I'm putting in
place a remote support requirements list for my office and there is going to be
a requirement for XWindows access to kit in the office and potentially on
I'm thinking on the lines of and ADSL solution but as the startup costs per
person aren't exactly cheap I need to justify this to my boss over using ISDN.
If anyone has any stats or case studies of similar situations I would be most
