Actually, there's very little similarity between VNC remote control
and Terminal Server/Citrix. The key difference is that the latter is
multi-user, while the former is just a matter of remote controlling a
single-user session on a remote PC. Something like VNC causes no
problems with running Finale, though there's no way I know of to
redirect audio output with any version of VNC I've ever used -- it's
strictly a video redirect and nothing else.

Citrix *never* worked that way. It was always multi-user, running on
top of the Terminal Server version of Windows NT. That is, you were
always getting an individual desktop for each user. That was the
whole justification for its existence.
The other big advantage of Terminal Server/Remote Desktop/Citrix is
that it uses the low-level GDI functions for sending data to the
remote computer. VNC is forced to send bitmaps because it is cross-
platform. This makes it phenomenally fast and responsive, and makes
it possible to work quite satisfactorily remotely over a mere dialup
connection. I've been working this morning on a client's Access
database using Terminal Server over my dialup connection (a 33.6
modem). It was just fine -- no problems at all.
The same could *not* be said for VNC over the same low-bandwidth
connection, or even over a broadband connection. There is always
substantially more latency with VNC than with Remote Desktop. The
latter makes it possible to work remotely without it being a trial in
comparison to working locally.
