[comp.sys.ibm.pc] Copy protection.

mms00786@uxa.cso.uiuc.edu (08/25/89)

With reference to copy protection, I have developed a small program, of use
only to a very small number of people. They will have to buy updated data
from us every month. I want to sell them data on a per machine basis, and they
are not too receptive to a site license. I also do not want to waste time
trying to implement any kind of copy protection.

My question is this: how can I make sure that they are purchasing one set of
data for every machine they are using it on? Do I have any right to inspect
their machines at all (I don't think so.) Apart from relying on a basic 
honesty on their part, is their any other way I can protect my interests?
There isn't much money involved either, about $20 per set of data, and I think
at most 50 machines on which it will be needed.

Thanks for all responses.
