File server solution for satellite office

Hi All  my company has recently branched out with a small satellite office of about 20 users.  The location is such that their ISP service is shoddy, so I have 3 ADSL lines running into a Tri WAN router that keeps them up and running for the most part.  I also have a site to site VPN setup, and an Active Directory domain structure with a DC in the external office.

The problem is file server access from the SO to the CO.  File access is very slow over the VPN.  I need a solution that would allow both offices to work on the same file with some sort of change control.  I looked at Double Take, but that is more of a disaster recovery solution.  I have a Terminal Server setup in the CO for them to use, but when they lose service on all 3 ADSL lines, which happens more than it should, they obviously cannot do any work.  

What we need is some sort of virtual file that is located in two locations and any change is synched between the two.

Current setup:
Single Active Directory domain  2003 native
3 domain controllers  one in satellite office
1 file server in CO.
Site to site VPN.
T3 in CO, ADSL x3 in satellite office.


Any thoughts?

Thanks,
Scott

Two thoughts... move the file server to a co location and have both sites read data from one server across the web using a public ip with a vpn... OR

At our company we had a similar problem.  We ended up going with a dedicated point to point T1 to the site and added Riverbed Steelhead appliances.  We have one server there that has the local user's home drives and acts as a print server.  Our backup and file servers are at our CO.  Before the riverbeds, backing up that remote server took 25-30 hours, but with the appliances it takes 3-4 hours.  As soon as I turned it on, I had a user call and ask what I had done.

I'm not sure what your budget allows, but riverbeds sure worked here.

KCTS - have looked at DFS, but I couldn't find any books, articles, or Admins with much experience getting this working in a production environment.  

In theory DFS exactly what I need, but you know how it is - what they say the technology will do, and what it actually does doesn't always jive.

Anyone using DFS successfully?

cmarandi - thanks for the link.  The Global File Sharing with SureSync looks interesting.  I am going to talk to them.  I will let you know what I find.

It's an expensive solution which will not work for everyone.
