Cool, I will try add the skining module. To be honest, I hope I can 
overtake the blend shape stuff, as all regarding characters and rigging 
( this includes best possible and fatest meshes export ) are my major 
field of interst.
If you know about corrective BlendShapes, I might be writing my Bachelor 
Thesis about a certain extension to this system which would yield 
perfect results at joints with more than one degree of freedom.

But we should talk about the curent mesh export mechanism, as there are 
some traps waiting :-) see new thread.

That can be done, but currently its only one TextField, does it really 
make sense for now ?

Now I think I can't follow you, neither  can reproduce the case you are 
talking about.
I have merged the function already, but just not commited, and it works 
as expected.

Before evaluating a global proc, the file where it is defined needs to 
be sourced, that's it. And as all settings are stored in environment 
variables, the UI does not have to be opened or executed, you can 
directly use the osg_preview command.
The only case is, when the whole system is installed, and no envVars are 
created, so we can catch this case, and generate the default ones.

As said, all that can be done without the UI opened, or the preview 
command existing in a seperate file.

Btw, I like it very much, that it is a Maya window :-) do you remember 
the discussion about having a direct connection between Maya and a osg 
Window ? :-)
