Would it be possible to make this a service so that one doesn't have to
bother with setting up a private instance of OSM on there computer. I
image the usage would be something like this:
1) A user chooses an area they want to test some scripts on, a clone of the
relevant parts of the database is made, but tiles will be shared with
the main server, until changes are made.
2) Users can upload they changes to there private space and see the
results of there changes (tile updates should be accelerated to aid in the
3) And any time they can request that they changes be abandoned and a
fresh clone is made.
4) To conserve space, if after a fixed period of time the private space is
unused, a diff from the clone point is made and everything else is

I can fairly quickly write a tool to take an OSM file and than a OsmChange
file or a JOSM style modified OSM file file and output a text based report
on the changes. It will be in Perl because I don't particular like or
