Hi Bart, the best option for this would be to assign the custer IDs to one
of the fields "user", "user2", etc. This way you can make the selections
simple and dynamic and also color the representation very easily.
If you have the IDs as numpy arrays (one per frame) you may be able to
assign them using the Python VMD interface. This may be difficult to do
with the precompiled binaries, but you can use Robin Betz's recipe to
simplify the recompilation:

Note: she may have an updated recipe, so I'm CC'ing her just in case.
