Well, the first thing is that we cannot possibly work in HEAD, because that 
will endanger the 3.1 release. And we can't work in make_it_cool either, 
because we need to approach stability by October 15. So we are forced to use 
our own branch, whether we like it or not (and we don't, for the most part).

I agree that merging can be a big problem. We'll try to minimize it by syncing 
our branch with HEAD regularly (planned is once a week). In an ideal world, 
we can - after consultation with the other KMail developers, of course - just 
dump our branch over HEAD, because we already have everything in HEAD. Then 
it's just to merge in make_it_cool into HEAD once that one stabilizes. And 
this can be made easier if the developers working on the make_it_cool branch 
merge HEAD changes into their branch as well on a regular basis.

Looking at the proposed list of changes in the make_it_cool branch, I can see 
only one right now that sort of clashes with what we need to do, and that is 
making KMail a KParts container. So we'll work together on that issue in the 
hope of achieving a common solution there. The other big change that we will 
have to introduce is an IMAP offline mode. The rest will mostly be additions 
to the user interface and judicious use of filters to pass incoming emails on 
to KOrganizer.

We'll write all this up in real architecture documents over the next 1-2
