Best way to setup colocation

We will be implimenting a colocation setup in the next 2 months and I would like to get some input on what will need to happen to make this work to maximum performance, availability and scalability.

GOALS
-Great performance between the 2 locations,
-Planning for if the WAN goes down and each location is no longer connected (high-availability).

SCENARIO
In this scenario we have location 1 and location 2.  Location one comprises of approximately 15 workstations/15 VOIP phones and location 2 comprises of 24 workstations/24 VOIP phones.  Location 2 will house the servers (SQL server, PDC, file share, etc) and I need to figure out what the best solution will be for site-to-site colocation connection Location 1's WAN link is 15Mbps up/15Mbps down and location 2 will be fibre - 5Mbps up/down burstable to 10Mbps.  I'm thinking of App-V for the accounting software, not sure about Exchange, and what about a SDC for Location 1 and what would I do about files stored on shared drives (replication of some kind)?

Maybe think about Centralizing what you can.  You could put the Exchange bridge head server in the colo, the mailbox servers in each site based on the users.  We keep our file servers local to the office they're used in.  You might also want to consider putting in a terminal server in the colo for local access to services you put in the colo.  This gives you LAN speeds and central access.  Hope this helps.

Thanks for the reply.  I'm leaning towards a terminal server too as the desktop applications required should have local LAN access to one another.  A second DC at the colo/Exchange bridgehead server seems like the route to go.  Local file shares also makes sense and I'll have to arrange for a separate off-site backup every night.

If anyone has any other comments please add them!

I think we're just going to go with an application virutalization technology for the critical applications and a colo-DC.
