Yep, there are. After your mail I just gave google a shot.
But none is specific for Gnome or other, just the same basic idea I 
already said in the other thread.

Here's the most promising candidates:

** Remote Clip - "Copy-and-paste data easily among Palms, Windows, and 
Unix using clipboard synchronization"
--> http://www-2.cs.cmu.edu/~rcm/RemoteClip/

A bit outdated but the more complete solution I found. It even has SSL 
for privacy, clipboard groups, invisible to the user once configured.

It's in Java. But it's GPL'd, so it should be ok to make a GPL'd C++ 
program out of it (this to avoid having a java vm in colinux).
What I like is they have all thinked out, so a good comparison project 
for any other solution.


** Clipster
--> http://clipster.sourceforge.net/

Using wxPython for the job. It seems only for windows machines, but 
ready to accept other platforms as well (by adding the platform specific 
functions).
On the TODO list is making it lite (the author acknowledges 6MB of 
unnecessary GUI code is quite ridiculous).


** Network Clipboard - "Transparent cross-platform clipboard 
synchronization"
--> http://netclipboard.sourceforge.net/

It's in development, not very well thinked (everyone shares with 
everyone on the same subnet), but could be exactly what we want for 
coLinux, i.e. the basic is made, just needs some coLinux related 
features added.
Against it is using QT3 in Linux - maybe too heavy - and seems to not 
cover all situations.


All others were single platform (mostly windows) or simply not worthy.

I didn't find any "production-ready" multi-platform solution, not even 
commercial one. That makes me wonder why...

About what I proposed (making a prototype using SDL), it will take 
longer than I thought. SDL has no copy/paste routines, just a sample on 
how to use the native engine (X, QNX, Win32, etc.) inside SDL.

At least now I know why the c/p mechanism has so many problems in X. 
There are two (plus one that is deprecated) ways of copy/paste in X, and 
both require that the programmer handles them (if not handled by the 
framework they use). As with many open source programs out there, lazy 
programs simply don't care.

In windows, the basic controls handle copy/paste "out-of-the-box" (and a 
requirement for the windows logo for the others), so there is no need 
for programmer intervention.
