Hi,
this is just a reminder that our current highest node ID is about
1.7 billion, and that it grows by about 0.05 billion every month.
This means that it is likely that by the end of 2012, we will have
reached (or be very close to reaching) the end of the 32bit "signed
integer" range (2.15 billion, or 2^31-1).

Software processing OSM data will need to either use unsigned integers
(which can be problematic in cases where negative values are also
required), or switch to 64bit integers altogether.
This is also relevant when dealing with database tables; depending on
what schema you are using, you might have 32bit signed IDs there as well.
osm2pgsql can be compiled with 64bit ID support but that is not enabled
in the standard binary distributions.
If you are in any way involved with writing software for OSM, it may be
worth thinking about that now.
Bye
Frederik
