[OSM-dev] renderd in a multi-user multi-style environment

for our German dev server, I want to give everyone who has an Unix
account the opportunity to install as many Mapnik styles as they want,
and make the rendered tiles available. I don't want everyone to run
their own renderd though!
I'm prepared to code the necessary changes to renderd and mod_tile but
would like to solicit your opinion before I do.
I think it could be feasible to have an /etc/renderd.d directory where
you can put as many config snippets as you want, each representing a
config section of the renderd.conf file, e.g. if you before had the section
then you would now have a file named /etc/renderd.d/default containing
We would then also need some way to make renderd re-read the config dir
or a Mapnik config file so that the whole thing does not have to be
restarted every time someone makes a change. The same is probably true
for mod_tile which also reads the renderd.conf file.
Also, we currently have one global planet import timestamp file, but in
a multi-style environment it is possible that some of them have their
own little database and thus have their own timestamp. We should
possibly specify the timestamp file in the renderd config so that this
is catered for.
Anything stupid or unworkable in this? Better ideas?
