Preventing an app from being run remotely

[Otis]

I have an expensive VB6 program that I do not want other people to operate
on a "time-share" or remote basis. Here is the scenario:

User A buys my program and sets it up on his computer with all the license
codes, etc. But now user A connects with others via TeamViewer.exe or some
other remote access program so that they can run his fully licensed program
without my permission and in the process he sells this "time-share" computer
time and makes money from it, thereby creating a situation where others
don't have to buy my program and can operate it with full-features enabled.

Is there anything I can do in VB to stop people from running/operating my
program via a remote connection? Is there any way to block remote mouse
operation or remote keyboard operation such that only a local mouse or local
keyboard has any effect?

Thank you.
