Visually group repositories into projects

I'd like to be able to visually group related repos (that may or may not be subrepos) into project groups. These groups should have a definable URI. This would be particularly useful when using a custom domain and wanting to be able to link to a specific set of related repos. I know that I could do this using static files on my BB homepage but that's a little bit clunky. Have I missed another way to do this?

Cheers

Greg
