So, I found some kind of program that allows data sharing between 3D modeling applications, as in having GIMP and blender open at the same time, editing the model texture in GIMP, and it automatically updating in blender. It might be possible to have it work over the internet too, so 2 people could be working on one blender model at the same time and seeing it update on each other's screens. Plus, its free.
Here are the 2 pages I found about it:
