This seems like it would be tough if your backhand instance is running
on a different port that the "advertised" instance. I think it doesn't
satisfy a general-enough case to include. I think that writing a perl
(and python and PHP and ruby, etc.) Interface to the mod_backhand
serverstats shared memory segment would solve all the problems.
Then you could do all sorts of really slick stuff in a status page and
it wouldn't require editing mod_backhand source -- ugh. It would also
open the application up to a little knowledge of cluster-wide resources
and a availability.
