What toolkit are you using?  vtkRenderWindowInteractors for Tkinter,
pyGTK, wxPython and Qt are available.  This is all in CVS but I think
it was committed about 5-6 months back.

To capture the mouse just add a new observer for the right event and
do what you need.

You are looking for a Picker.  Try one of the vtkPickers.
