Um, RyanMuldoon, I can't email you as you suggest because I see no email link on your page or from your company webpage.. :) But stuff about clipboards and X for Gnome off the top of my head:
- X Selections, X Cut Buffers, and Emacs Kill Rings gets mentioned a lot
- the Googlizer is a tiny program that uses X-selection in Gnome with some GDK stuff which is covered in the GTK+ docs
