Theres another trick that could wrk - gurus here please correct me if iam
missing anything

If ur STA dlls are actually going to run somewhere else eg in a remote MTS
machine (ALWAYS)- u would be naturally only having to talk to the proxies
naturally in which case u could do something else (it is WORKING for me)

modify th regsitartions in of the dll in the machine in which ur process is
going to
run and set the dlls to be - threading = Free and set the location of the
dll in
the inproc32s default key to be empty

Use coinitializeEx and initilize to COINIT_MULTITHREADED -

Now make sure u never call any of those interface pointers simultaneously

- if u can ensure all this - then all ur proxies will be created in a single
mta
apartment (only for a single process) - which means that u can freely share
the data that is returned from any of those method calls between ur differnt
threads or whatever -

and no need to do any marshalling of the data - can easily PostthreadMessage
to send the data anywhere u like

i have an exactly - similar situation - and i have touse PostthreadMessage
too
to send the data generated to differnt threads for execution -

good luck
arun

NOTE - u will not be having STAs and its message ques in this case - and
the PostthreadMessage i talked abt is used to sent message to threads
created
by u - not any STA message windows etc
