I am working on Win32 Ole support in ruby. The main thrush is to allow ruby
to be at both sides of the equation. I have been using some bits of the
current Win32 Ole module but am rewriting many bits

I have it mostly working now so you can create Ruby object via IDisaptch

e.g.

Set MyObject = CreateObject("Ruby.MyClass")

And then make calls to the ruby Object.  As you can pass IDispatch objects
back to across the interface I am using some of the Win32Ole module as a
basepoint for that side of the equation.

I think this good COM support VITAL to make ruby really useful, and
mainstream on Windows, and I am keen to see more people take it up.   And
it's a nice easy way to create com objects to boot (even if currently it
only supports IDispatch )
