Doing it that way is not very effective. Its no big deal to pass someone
your customer number giving them the code and the number allows the code to
run on any computer. I believe what needs to be done is to use the builtin
function CustomerID to retrieve from TS the customer ID and compare to a
hardcoded ID such that unless that version of TS is running on that customer
ID you will not have a match. For TS6 and TS7 that is probably fairly secure
but for TS4 and TS2k it is not as secure but slightly better than what you
proposed.
