Yay! :)

Hmm, given my scenario, this might work. Basically I want to have my
laptop be able to travel between work and home and have a 'master' at
each place. Inverting that idea and making the laptop the ;master'
Icould instead have a 'slave' at each location and have the 'slaves'
sync from the laptop.

Now, the question is, can I then have clients which check out from
the 'slaves'? And if so, what about clients of slaves which need to
make changes, and commit back the slave they checked out of?
(my current ideas/requirements don't include this scenario, but I can
definitely see where it might be desirec feature for a lot of people).

Hmmm, that might pose a small problem, however, if my laptop is the
'master' in this case, then it's unlikely my home system will ever
need to commit when I'm at work :)

Absolutely! Take your time and do it right! :)

I might be interested in playing with it. If I can get it working, I
can at least provide feedback as to what breaks down in my usage
model.
