I would NEVER use highly encrypted VPN tunnels between locations where accessing (reading and writing to) databases was going on. The performance would just totally suck.
Better off with private point to point OC-3 or faster connections between such sites.

L2VPN... or L3VPN is you really want to bother with it ( but for a point to point, L2VPN is way better )... No point into encrypting. MPLS will to the flow segregation for you.
Your OC-3/STM-1 is so has been when you have Terabit connectivity ( and Turbine... well PNAP... has Terabit connectivity ).
Come on in a few months I'll have almost the equivalent of an OC-12 at home. ( 500Mb down, 200Mb up... that is If I don't want to switch operator for my broadband )
L2VPN, from the user point ( aka the company with two sites separated by lots of distance ), is a seamless LAN...
L3VPN, is two separate LANS tied with two routers...
But in between you can have 10 or more routers carrying the packets along with packets from other companies...
