I've been working on a c++ parser of hg's revlog format. I think I 
understand most of the format now, but some parts are missing: It needs 
an implementation of hg's delta algorithm and some more magic to link 
the manifest table with the file data files and general handling of all 
that. A hg checkout keeps lots of files in revlog format, maybe a bundle 
is easier to manage, but I didn't look at those yet.

With those additions, it should be quite easy to fetch the manifest 
tables, their changelogs (including data that would end up in author and 
date certs) and all full versions of changed/added files. From there, 
the monotone data could be synthesized.
I haven't thought much about the other direction, but there are some 
issues with the flexibility in how monotone stores metadata (we can 
extend the metadata of committed revisions using certs, hg doesn't seem 
to be capable of such manipulations)

I don't have the time to work on this until late summer, but I could 
post the (not cleaned up) parser bits that I have somewhere.
