I wonder if someone is maintaining precompiled mappacks derived from OSM tiles server.

I know www.millions.ca/~stacy/osmtiles.tgz, but i wonder if there are truly precompiled mappacks i just need to untar on my openmoko freerunner.
It would be awesome to download, for example an "Europe" mappack that holds entire Europe.

If not, it would be a nice idea, to create a project around exactly that. Maybe it is possible to cupple that with opengeodb to automagically know which and where are big cities that need more detailed maps. This data maybe could be feed into osmtiles so it generates the mappack.
Several mappacks may be combined since we just need to untar files. Since the detail levels are maintained in different files, low-res tiles will not overwrite high-res ones - mappacks will automatically enhance each other.

Would that be a good idea? I just cant believe i am the first guy who has this. Something has already to be out there!
