I use a lot of booleans in my modeling for poser, so far I haven't encountered too many problems. There's one thing I always make sure though, after I'm done with all of my  boolean operations, I always triangulate my model and save the triangulated version as a new file, just incase I want to go back later and change things. Poser will now import the model just fine, no matter what crazy kinds of booleans I've thrown unto the model.

Due to the childish TOS changes, I'm not allowed to link to my other products outside of Rendo anymore :(

Food for thought.....
