the ultimate fallback would simply be a URL, with which Browse
could take you to a (hopefully friendly) source browser on the
web somewhere -- to browse CVS or git, for instance, or even just
to an upstream program-specific website where more information is

as you implied, flexibility is the key.

an addition to activity.info, with sensible defaults, would be the
best bet, i think.  default behaviors could include going to bundled
source, as you've implemented, and/or using the "activity_source" URL
that many activities provide on the download page on the wiki.
