I implemented it by creating an HGLOBAL stream then locking the global
and doing a memcpy. Not especially high performance but it works and the
code is well insulated. I found the necessary flags were in the loword
of pFlags.

Hehe, yes, this sounds possible. Well, no matter, I was just a bit
curious.

Anyway, dispatch variant marshalling works now. On to the next crash :)
