[Bf-python] Ok, heres the status of the EMesh code.

[Campbell Barton]

Hi, Im with you on most things, a few areas of confusion, can cant 
change the vertex data, ie- Location.

But you should be able to select the verts and use a grab macro to move 
them? - Rotate Grab etc.

Other things that you should be able to do are modify edge weight and 
seams on selected edhes.
Ctrl+E, Shift+E - So it works just like in Blender.
