Now that the initial import is finished, it might be good to get the 
ball rolling on the rendering side. The fact that it still hasn't fully 
caught up shouldn't hopefully matter too much, as later it will also 
constantly be updating to keep up with the minutely diffs.

I guess there are three things that would be good to get working 
initially. mod_tile, the static export script, and the osm-render tool 
for testing styles on the login-servers.

In all three cases mapnik is needed. It looks like mapnik is already 
installed on nightshade, so potentially the osm-render tool might 
already work with that? It looks like the version installed is 0.5 
though and I think the current version of the OSM style sheets need a 
newer version, possibly 0.6.1. I don't know how far back you would have 
to go though for them to be compatible with version 0.5 again. 
Never-the-less, it might be nice, if possible, to update to version 
0.6.1 or 0.7.

The export script[1], which is used for the static images in the Maps 
wiki plugin is a simple cgi script in python, so hopefully should be 
fairly easy to get working, as long as the python mapnik bindings are 
installed on ptolemy. Later on, the export script will presumably need 
to have a proxy in front of it (it should set the correct http headers 
to support that already), as unlike mod_tile, it doesn't have any own 
caching built into it and renders all requests on the fly.

That leaves mod_tile and renderd. Will it require a lot of work to port 
it over to to run on ptolemy? What can be done to help with that?
