I'll freely admit I'm focusing on just those two paras out
of a fairly long email, but topgit does precisely this.
I've started to use it, and it seems to do the job well.
When a feature branch gets updated, you just check out what
I will call "t/all" and do a "tg update" and it picks up the
new stuff.

So the everyday stuff works.

The only sort-of-open question, right now, is how do you
remove a dependency when one of your "local hacks" grows up
and goes off to college.  Er... I mean gets accepted
upstream :-)

My guess is that as long as all these local hacks are indeed
local, the branch that represents the "sum total" can be
blown away and rebuilt when that happens; you'd just list
all but the recently graduated feature as dependencies.
