A couple of questions about XUL on the tablets:

Q1. Hidonized XPCOM? I guess it is XPCOM, but what I am trying to ask is if it will be possible to 'auto-hildonize' XUL apps so that the same source can be used for XUL apps running on Win/Lin/Mac/Tab?

Q2. Will a XUL runtime be shared between all XUL apps? MicroB and/or FF browser + XULRunner apps. (This seems to me to be an important issue for portable devices with a small amount of memory and one that Python and Java both fail to meet).

A more general question:

Q3. XUL has always looked really interesting but I have never got my head around it enough to decide if I want to invest time learning to use it. That, plus the vague feeling that it might only be an internal project used by Mozilla - not really a well-supported, well-documented development environment. Was I wrong about this, or is the outlook for XUL about to change?
