asterisk users - May 2013 - Asterisk High-availability/failover solutions

Hello all.

As part of a project I'm working on to migrate from Asterisk 1.0.11.1 to 
the latest LTS version, I'm looking into providing a HA/failover 
solution for the new Asterisk installation I'll be deploying.

It would appear my best bet would be to use the R850 Digium appliance.  
Does anyone have any experience running one of these devices along with 
AsteriskNOW?  I ask because apparently from what I gather from the 
rseries admin manual, it's required to use flat files vs. SQL -- and 
obviously AsteriskNOW uses SQL.

Failing that, I wonder if AsteriskNOW is nothing more than Asterisk 
11.3.0 + FreePBX?  Would I be fine installing 11.3+FreePBX?  I'm mainly 
wondering what the differences would be from AsteriskNOW vs. a vanilla 
install.  I'm currently trying to see if I can find any difference using 
virtual machines, but any info would be extremely helpful and 
time-saving :)

Thanks!
