My best guess is that it can only stay alive for the life of the page,
but I have seen some pretty amazing stuff with JS in the past year or
so.

I assume you need some way to serialize the processor object and I don't
see any way to do that other than the XSL's XML representation upon
which it was created. 

I also wonder how much would be gained by reading back in a serialized
processor object (if it were possible) versus just rebuilding a DOM
(free threaded in MS's case) and creating the object. Probably
something, but maybe in the 100s of ms range???

After a /quick/ look at Silverlight, it looks like it does not create a
DOM, rather it reads the XML file stream. It looks like java's SAX.
