[FreeNX-kNX] Performance of RDP over NX?

[S. Gerstenberger]

The company I work for is doing a project.  One aspect of it involves
running RDP over a 56k modem ppp link while simultaneously using the
same link for database updates.  I have my doubts about the usability
they are likely to see out of this arrangement.

Though it is (fortunately) not my project, I'd like to be able to step
in with a solution if they find that performance is unacceptable.  But I
want to be sure that my solution will really have significant benefits
before I propose it.

Anyone out there running rdp sessions over NX over a modem?  How much
more responsive is it than just using the MS rdp client?

Thanks for any info.
