Agreed, this would be the far less mad idea for rendering, especially if OSM picked up 1 or 2 more machines to host with the rest.

The last time I was investigating this, things got stuck with Squid. I was trying to implement cache invalidation on a list of cache objects, using the squidpurge tool, and it wasn't working brilliantly. Help welcome.
