How to create COM Servers with IID_IDTExtensibility2 interface

[Christopher Paulicka]

Mark,

Shouldn't this be possible?  I know that Dolphin Smalltalk allows this?  And
the implementation within their VM doesn't imply any particular magic?

Of course, I'm not sure I could do it.  I just wanted to know why it was
difficult.

Does this mean, if I want to make an implementation of an interface for
callbacks into an existing system, I'll have to write a pyd that supports
that interface?
