For it to work (for current changesets) though, we would need a
continuously updated full history database..

Doing the import is one thing, doing the update is a whle different thing. Both 
being mixed up into the same application results in a lot of not-so-nice and 
not-so-well-optimized code (see osm2pgsql). For updates you'll need a different 
cache strategy, a different level of access to the database and different 
algorithms.

For me, cleaning up the importer, adding multipolygon and route-support as well 
as optimizing the importer to be able to handle full-planet-full-history 
imports is higher on the priority list then an updater, and you'll, have to 
live with that ;)

I'd love to see those tools sketched out on the data we have already. 
Developing a nice before/after/diff app is a really complex task and maybe if 
the app is finished, the updater is, too. Don't wait for other tasks beeing 
completed if you could work with the things that are in place already.
