As DVCS are gaining popularity, projects tends to divide to small 
distinct repositories (which is partly due to the incapacity of 
the main DVCS to retrieve sub-directories of a given repository).

As a matter of fact, code-review tools must be able to span accross
several repositories, which is the case of the reviewboard. 
But a simple feature seems missing : in the global review table 
there is no column to pin point to which repository a particular
code-review applies.
 
Fortunately, this do not take long to patch.

I'm sorry if this was previously discussed or even resolved. I'm 
using the last public SVN code source, and this issue doesn't 
seem to have been worked out.
