I have a project on my plate which will involve potentially hundreds of PG8 databases in the field which will need to synchronize data with a central database. The company is a secular nonprofit which delivers medical services to underprivileged kids as well as to disaster victims like those hit by Katrina. We have six mobile medical units there now as a matter of fact.

Some of these databases will have 24/7 net connections; some may not even have telephone access for days so traditional database replication techniques won't work. I've not found any third-party software yet which could help us here so I'm proceeding on the assumption that we're going to need to build it ourselves.

This sort of database topography is virgin ground for me but I'm guessing that others here have encountered this challenge before and will have some tips/advice/war stories to steer us in the right direction.
