@Chip Bennett -

Ok... but under the terms of the GPL, if I buy a copy and obtain your source I am then able to redistribute that source code to the public for free without charging a fee. That is to say, if I want to buy a license, I can then post the plugin to my Web site and allow the masses to download it for free... without every paying pluginbuddy or myself a dime, if i so choose.

This brings about two points... if not ok with that (and I don't know why anyone who demands payment for binary code to obtain the source code would be ok with it... otherwise, they would just distribute it freely themselves), why choose a GPL license? Furthermore, how do you actually license the software to be used on 2 sites, 10 sites, etc. If I purchase a license and then have the ability to redistribute the software freely, if I so choose, doesn't 1 license in fact equal unlimited licenses as I can redistribute the software to each and every client I build a Web site for?
