Bill,
Terminal services simulates a kind UNIX or whatever mainframe environment.
Think about the classic VT100 for that. (See at the end because it is not
really doing that, it looks alike)
http://vt100.net/
This means that your programs can be as shared data on the server (not the
actual processing parts), for the typical user information should be taken
steps to hold that. Therefore needs mostly a terminal service a hug amount
of memory. With more users you need at the moment to have more computers
(balance loaded placed). Depending on the applications is 10 to 20 mostly
the maximum for one server. (I don't know yet the effect of the 64Bits
computer on that).
At the moment you can buy modern VT100 terminals (the name for that) which
can be connected to Citrix.

It has only memory to hold it logic for the keyboard, the mouse the screen
and connection.
The back point from this is, that Unix processes are mostly made for this.
MultiTiering their data use or whatever use, so make it possible to let the
users share that.
Windows applications are not directly build for that approach however more
for the Client Server approach. Here you see direct the advantage from a
multitier in such an environment what as you probably know from me, I don't
find direct an advantage in a windows environment.
Before you misunderstand me. Terminal sharing stays a Client Server approach
it is not a real Unix design approach. The Terminal Server is doing all the
client processes as where they on the clients computer user by user.
I hope that this gives an idea.
