We will have to convince Addon authors to convert away from XUL, so there needs to be
documentation or workshops helping to get away from this. And obviously we need a
transition time where "both" technologies can be used concurrently to find out about
performance / compatibility issues. According to the timeline you give below, there is
not much wiggle room there.

I am using Android Gmail App to access my email in parallel with the more comfortable
Thenderbird on my desktop when I actually try to get some work done. Most email
providers already allow web access to their emails. But a unified Thunderbird frontend
on Android and Firefox OS would sure be nice.

can you elaborate what you mean? Forking would make XUL-based development impossible?

for the web app, will there be local storage? a "gloda-like" repository that can be
stored on the hard drive? will the data be cross compatible with any other desktop

Any plans on who from the Thunderbird team could / would lead development. Are we
going to get some help from the Firefox team?
