Somehow I guessed :-) 
Why do you think I mentioned it in 1 mail together with a task for you ? :-)

Easy: look up the method in RTTI - you'll get the address.
Push all arguments on the stack (see Remobjects/Innerfuse PascalScript on
how to do this, you need some assembler for it), and return result value.

2 days, tops. 

Lots easier than writing a MGM or MVM (heck, don't remember all these acronyms ;)) 
for tiOPF :-)
