I agree. The less hardware we need the better.
So here's one further question: I always catch the area I'm mapping 
completely anew from the server. What if we had a kind of a "diff"? 
Imagine I keep my osm data locally. If JOSM starts, it loads that data 
file and then asks the server to deliver *only* the data that has 
changed since the last sync. This at least would save a lot of 
bandwidth, wouldn't it? This even is valid for the future as the user 
base grows.
