The Network Clipboard is a Java (that means cross platform!) program that lets you basically share a clipboard between multiple users. I've used it in various situations, like teaching and also group work projects. The latest version (1.4) has some big bugs that still need to be worked out, but it's coming along nicely. Try version 1.2, which is the latest stable version, if you want something that behaves well.
I've searched high and low for a program that can edit the normals of an object. The program that I normally use for modelling, Wings3D, does not support editing the normals of models. There has been more than once that I've really wanted/needed this and I can't do it. Hunting through a gigantic file for the data that I want to edit is useless. Some expensive editors, like 3D Studio Max allows it, I think, but I don't have $4000 for it. So I'm planning on making a normal editor that is free. Information can be found in the projects page below:
