Hey, I think you have a great thing going there. Shield the company from ongoing technology upgrades, very important. Don't let them know about the Internet, that will really screw this opportunity up. If necessary, lock the doors and cut the communication lines out of the building.
1. Suprise them with the concept of Windows 3.11 for Workgroups.
2. Introduce the power of FoxPro 2.6
3. Amaze them with the speed by which you can program in this NEW powerful language.
4. Wait 3 years... or until customer gets bored.
5. Introduce new amazing operating system Windows 95
6. Bring them up to speed with Visual FoxProg 5.0 (3.0 sucked anyway and you don't want to torcher yourself.)
7. This process could takes years... You got a great thing going there.
