Imi is currently working on mutli-layer capability for JOSM. Without  
knowing exactly what he's doing, I expect the outcome to be very  
useful for import jobs - load OSM data on layer 1, load import data  
on layer 2, and work on import and/or OSM data until you're happy,  
then upload. As long as you have both layers separate, it is much  
easier to work with the data, and potentially throw out some bits  
from one and some bits from the other... the layering is lost once  
you upload the stuff, unless you manage to re-create the layers when  
downloading OSM data ("everything with source=TIGER in extra layer").
