I think this may also need a repos group support.
Each project have one (or many) repos groups, each repos group have many repos.

http://hg.example.com/myproject/release-repo
http://hg.example.com/myproject/qa-repo
http://hg.example.com/myproject/dev-repo
http://hg.example.com/myproject/tries/try1-repo
http://hg.example.com/myproject/tries/try2-repo

and 'myproject' is the name of the project as the repos group name.
and 'tries' is also a repos group under 'myproject'.
