Sergio, have you been working on this?  I think it could be very cool.

The thing about PyXPCOM is that it's fairly heavyweight--you get all of the
benefits of Python's "batteries included", which is great, but on Windows
your extension will probably have to include an embedded version of Python
(unless you choose the harder but more extensible route [1]).  And
regardless, putting a CPython VM in the Mozilla process is going to eat up
another few megs of memory.

The potentially nice thing about using TinyPy, though, is that at ~64k it's
really easy to pop in a FF extension and just use as an alternative to JS,
perhaps even creating Python standard library proxies that just delegate out
to XPCOM.

Mozilla is also moving away from XPCOM, and a lot of their new code is being
developed as JS modules [2], which, as far as I know, are completely
unreachable from XPCOM.  So a bridge between TinyPy (or even CPython) and
Mozilla using something like nsIXPCScriptable [3] might be more desirable,
not to mention easier to use.  That's just total speculation on my part
though. :)
