You can network over USB using equipment from people like
http://www.ezlinkusb.com/.

Don't know if the protocol is TCP, and it only appears to be Windows, but
what the heck, it's a possibility.

- Missing an exposed automation model for client or server.
- Open source, so if you want to modify or enhance it, you can.
-Supports only 1 server session on Windows server platforms

No USB as late as 10.0.
- Allows filecopy and console connection.
- Can be accessed from a web browser if using the ActiveX or Java control.
- Client and server both have small exposed automation model.
- The Java client offers the potential for remote connection from any client
supporting ca. 1997 Java technology; works fine on Windows/Netscape 4, have
heard that it is fine with Macintosh clients as well.
-single user session only.

Yep, needs a TS CAL as well as the Citrix licenses.  Coming from a Unix
system,
has identical licensing requirements to a WIn9x system.

- Don't know about USB support on this either in latest versions.  If there
is a
version in the works for use on top of .NET server, it is very likely that
it
will support USB.
- Supports drive mapping and printer redirection.
- Good automation model, client and server side.
- Multi-user computing
- native clients available for DOS, Linux, Windows, Macintosh, OS/2, and
possible some hand-helds.

*Depends on the version. What they have in common:
- It's free if run in admin mode.
- Doesn't support USB.
- In application (multi-user) mode, any Win2K/XP Pro  systems get issued a
built-in license so there is no additional cost there.
- Native clients only support Win32.  There are (licensed) versions for
Macintosh and DOS, and an open-source client (rdesktop).
- Extensive automation model, client and server side.  Server versions
moving
from NT 4 TSE to .NET server have significantly increased exposure via WMI
and
ADSI.

 *Current (Win2K Server, RDP 5.0).
- If used with the latest universal client, supports automatic printer
redirection.
- Color depth limited to 8-bit.

*The .NET version (RDP 5.1) is in Beta 3 at present.  It includes:
- Client-side drive mapping (seamless, works pretty well, but could be a
nightmare for low-speed connections).
- Automatic redirection of printer and COM ports
- sound
- 24-bit color
- direct to-console connection
-  USB and scanners - talked about, but this is _not_ likely to be a feature
in
.NET.
