I just saw there's a bitbucket extension for hg.
You can get it and use it to create repos, look at forks, etc etc, by grabbing it:
pip install lxml hg clone https://bitbucket.org/birkenfeld/hgbb
And then you have to point to it in your .hgrc:
[extensions] hgbb = /home/mturk/Packages/hgbb/hgbb.py
If you read the top of hgbb.py you can see the config options, etc.
Anyway, really cool -- especially looking at incoming/outgoing fork changesets!
