This is not so much an OpenVPN problem as a problem with the program/database you're using.
If the native file format of the application is the only way to store data, you need to use terminal services as Les suggested.
Otherwise it might be worth a try to see whether you can use an ODBC connection and put the database on a MSSQL/Oracle/MySQL server.
Using a database server would certainly resolve your problem.

Subject: [Openvpn-users] Trying to open a 100MB File Over VPN
I'm using OpenVPN to have a remote user access a QuickBooks database on the internal network.
1. The remote user is accessing the Internet over a DSL connection.
2. The QB database is approximately 100MB
3. The computer that has the QB database is connected to the internet over a T1.
When trying to open the database it times out.
When moving other smaller files or opening other smaller files its ok.
Is there a way to improve the OpenVPN so it allows this to happen?
