May I ask what the practical advantages to using tirex over renderd are? 
It sounds like it has a nicer architecture for when you whant to extend 
it and do more complicated things. But so far I am not sure any of those 
extensions have been implemented or for the moment are necessary for the 
toolserver setup. So given that tirex still seems a bit experimental, it 
might not be a bad idea to experiment with it on dev.osm.de for the 
moment and continue to use renderd on ptolemy for the moment. One thing 
that does look quite interesting is tirex's ability to automatically 
restart a crashed render, but then it shouldn't really crash in the 
first place and I haven't heard of any stability problems with renderd 
on tile.osm.org yet.

The min and max zoomlevels also need to be specified in mod_tile, and I 
think that might actually be hardcoded in the source. So having a 
flexible renderd alone might not help.

Are there any plans on setting up the live cluster? It does in some way 
sound like those services shouldn't necessary be on the toolserver, but 
then it makes sense to test it on the toolserver first and to me (not 
really knowing anything about the wikipedia side of things) it appears 
as if WMA and geohack are still running on the toolserver too, even 
though they have been "in production" for a while.
