On a 64-bit machine:
Can a 64-bit application call a COM server (out proc) which is running in 32-bit process?
What about vice versa? (32 bit app calling 64-bit COM out proc server)
Thanks!

The whole point of out-proc COM is that the two processes interact via RPC (usually LRPC), so it doesn’t matter at all which bitness each of them has.
We used COM+ surrogate for forcing 32-bit in-proc components into a separate process for the only purpose of consuming them from 64-bit clients many times – with all necessary stuff for marshalling present it works without any effort.
