Are you at any time considering a "Demo" –– you know, the way shareware was intended to be distributed?
"Shareware is basically "try before you buy" software. Unlike software marketed through normal retail channels, where you are forced to pay for the product before you've even seen it, the shareware concept lets you try a program for a period of time before you buy it. Once you have tried a shareware program, you know whether it will meet your needs before you pay for it.
Shareware programs are just like programs you find in major stores, catalogs, and other places where people purchase software - except you get to use them, on your own computer, before paying for them." –– Copyright © PC Shareware, Inc
