Looking for way to replicate master db to multiple mobile databases

Hi,
I'm looking for a way to replicate am master database to multiple (100+)
databases that are taken in to the field. Currently for each laptop we dump
and load the tables. However,there is only a small percentage of data that
changes on a frequent basis.

I've been looking around and come across pyerplica, londiste and bucardo -
the documentation on most of these is fairly sparse. It seems that Bucardo
may be the best bet - at least initially.

However, I thought I'd see if anyone is doing something similar and what
thoughts there might be out there as to a better way to accomplish this.

Thanks,
Bryan.
