Low latency across large distances

Hello experts - I work for a small architectural firm with two offices connected via MPLS.  This gives us a very fast, low latency connection which allows us to work on Revit and CAD models between offices.  It's expensive but not excessively so, mostly because the two offices are not very far apart.  We're likely to acquire a new office in Florida (I am in PA/NJ).  I need to find a solution to network these additional offices together with a low latency connection.  I don't know if MPLS would work well across that great a distance and I don't think my current provider operates in FL.  What other options do I have?  I find that VPN users who are working from home even on fast internet connections don't have a very good experience trying to do CAD work because of the latency and I'm concerned just doing SSL or IPSEC VPNs using local FL providers won't be low enough latency to work effectively.

You aren't likely to find a low latency dedicated connection to Florida that will work as well as you would like, simply because the infrastructure for something like that doesn't exist. If you were looking for a connection between New York and Chicago, or a similar large metro area to others, you would have more luck, since there is infrastructure in those areas that is designed for low latency connectivity, but Florida doesn't really have much like the low latency links that exist between major Financial industry hubs. And, to be honest, many of the ISPs in Florida are pretty terrible for latency and throughput (from my experience, which is limited to the Palm Beach area, so it may depend on which part of Florida the new office is in). You may need to look at solutions that will let you sync data between sites so users can work on it at multiple sites without having to connect to a specific server in a different location to do so.

Yeah, kind of what I was thinking but I figured it would be good to ask.  The other way to go here is to put the data in the cloud, Autodesk has a bunch of services centered around this.  I'll keep this open for a bit in case anyone else has some other ideas, thanks!

Adam Brown has given you good advice.  
You may want to think of "solutions that let you sync data" as having a local cache.  
You work out of the "cache"/local files and the synchronizing is done in the background.

Of course, it may depend on what you're trying to do.
Running programs isn't likely - or you could use a remote capability like Windows Remote Desktop "RDP" or GoToAssist or .... but the HMI interface may be too slow for you there.  It does avoid the file problem.
Accessing data files is much more likely - so the idea of caching and syncing.

We do that for VPN users now, VPN in then RDP to their desktop.  It works ok since all the heavy lifting is happening here but its not ideal.  Can't really do that with the new office, too many people.  I'd have to do something like virtual desktops which gets hairy using CAD applications due to the high system requirements.

So, you're back to cache and sync; i.e. local file copies.
While the information provided by Adam Brown may be true for Palm Beach, In Jax, there are several providers that deliver low latency connections. Comcast has a pretty decent Layer 2 service that I have used in the past for VOIP and high data volume which appears to have a extremely low latency and Jitter. I am not sure of your area, but I would recommend that you stay away from TW Telcom which is another provider of Business class MPLS in FL.

If Comcast Layer 2 will work for Real-Time MRI and Radiology imagery it should work for CAD application.
