There's already geotorrent with 33 datasets for full datasets. My thoughts for distributed map services would be to just devise a set grid at different resolutions and pass WMS requests through something like the coral cache. That way if other applications use the same WMS and make it so that their requests only use the same gridded tiles, you can start to develop a network of cached queries. Basically a fully server end version of what ka-map does for cacheing -----but this is getting off the current topic......
If we can distribute the work of maintaining high quality datasets and also provide good macro style scripts, then anyone can update the datasets as they can just start exactly where the last person had left off and grab whatever updated data directly from NIMA or the Census or whomever....
