Does nobody know about the -Djosm.home=<dir> parameter you can pass to 
JOSM when starting up? It can be put easily in a shortcut. I've used it 
all the time during imports. When doing "integration" you only need to 
download the data in another JOSM instance though, but one is 
downloading data all the time when working on OSM.

I find it convenient to have separate accounts, so I can distinguish my 
survey/tracing work from my import work, and the different imports from 
each other. It is also good as a safeguard when data turns out to be 
non-compliant with the OSM license. The requirement to have different 
e-mail accounts is strange and unnecessary, especially if we encourage 
users to use different accounts for imports.

As for having a multitude of accounts, I see no problem with abandoning 
them once the import is complete.

This issue gets way too overblown.
