>>VFP does apartment model threading (it has to to even work with MTS), but still has problems with method blocking. Since the capability to field more than one request simultaneously is one of the key advantages to an MTS app, this makes VFP COM object virtually useless with MTS until this is fixed.

>Oh... I thought the capability to field more than one request simultaneously was apartment model threading (in and of itself). I don't think I've read anything about method blocking, where's this fit into the distributed app picture?

Roxy, I've been reading a great book called "Designing Component-Based Applications", MSPress, ISBN 0-7356-0532-8 by Mary Kirtland. She is the program manager of the COM group at MS. It explains apartment model threading...but I need to read it a couple of more times before I understand it enough to explain it to someone else.
