Enterprise rollout - 50+ Distributed sensors with centralized managment / alerting / analysis

[Shon <mindphuzz () yahoo com>]

I'm looking for some enterprise implementation advise.
We have around 50 field offices that we'd like to
deploy Snort in, along with a fairly large corporate
office deployment. The 50 field offices are WAN
connected, usually with a T-1/VPN solution.

My question is how to deploy Snort so that I can
manage the alerts/reports from all of these sensors in
one location?

> From what I've seen the most common solution is to
have the sensors all log to a common DB, but I assume
this solution is impractical over WAN connections with
limited bandwidth. So how do I get around this? 

I know that SnortCenter can manage the sensors, but I
can't seem to find a solution for the analysis that
doesn't involve connecting all the sensors to a
central DB. Is there some form of DB replication I can
use? Is there an add-on solution?

How are others handling this problem?

Cheers,

-Shon
