>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?
