thats true in terms of design and in fact even guid values - nsISupports 
and IUnknown use the same guid. However they have diverged quite some 
way in terms of implementation.  You can't load a COM component using 
the xpcom infrastucture for example.

I don't think it wuld be any easier to build under .NET. You would have 
to essentially re-write the COM interop layers for XPCOM. At one stage 
you could build xpcom components in java - I'm not sure if that is still 
true, so implementing a binding is certainly possible.
