If you don't want to make any changes to your software, I would
suggest that to use Terminal Services. This would permit your software
to run on the LAN and at the same time permit the user to connect
remotely via a fast secured connection. Also, the remote users would
be able to use their local printers, and even transfer files between
their local computer and the LAN (this will depend on the remote
settings and network/user security settings).
