That is interesting and explains why access to the Pi isn't as snappy as
access to Windows boxes that are some distance from the user. This may also
explain why LXF only described SSH and VNC and never mentioned xrdp.
No matter; I'm satisfied that it works well enough to try things out and I can
use SCP and plain ol' network browsing to exchange files if need be.

Strangely enough, only the client and the Mozilla plugin appear to be in the
repository.
I might have a look at this in more detail sometime and see if anyone has had
any success porting it to the Pi.
