that's because a large portion of such software is actually executing within
the host's object model, ie your talking about JITing relatively thin wrappers
around COM objects.  fast or not, it dang sure isn't cross-platform or scalable.


No thanks; it's probably just more spewtum.

of course.  this whole excercise is designed to make the linux/java community
anxious.  and well done, i must say.  even if the whole thing dies down after
JavaOne, MS will have gotten their money's worth (if, in fact, they have spent
any money on transvirtual).

As for TVT selling out, i hope you are right.  I really do.
