Just throwing an idea around, you could also take an orthogonal approach 
where you would do that *outside* of the VCS, for example in a web-based 
application in which you could indicate a lock "intent" on the files. 
That could certainly be done in Trac by a plugin on top of the mercurial 
plugin, and you could even imagine showing the lock acquire/release 
events in the timeline.
