Exporting vertex groups as individual objects ??

Hi all,
I am not sure this is the right place to ask but here is my question.
I 'd like to export vertex groups (from a rigged mesh but could be unrigged) as individual objects. Would be great if this was possible in COLLADA format.
Is this possible from Blender ?
Thanks for your help

Thanks a lot.
I just need to figure out how to use this now, as I am not used to python scripts.

Open text editor in Blender (shift+F11) or use the scripting layout from the top header, create new text block, paste code in, select objects, and press “run script” from the text editor header (or alt+P when the mouse cursor is over the text editor).
