So, my next problem
What's the status of custom marshaling, especially out-of-process? Is it supposed to be quite well developed (in which case I am trying to find out why our case is different) or is it still only just started?
Yes, custom marshaling should work. Out-of-process COM should also work, as there are a number of programs that rely on it, including InstallShield and embedding in Word. It is also quite well developed and very simple.
If you have a specific question or debug logs I might be able to help you more.
