Protect WordPress Plugin?

Hey all,

I use TurboActivate for all my Adobe AIR apps and it's fantastic. However, I also write WP plugins and have been trying to figure out if there is any way I can protect them with the same method?

Any thoughts on how (if at all) this could be done?

Well, you can't actually do this. Not unless your Wordpress plugins are just a thin wrapper around PHP extension code (C / C++). In that case you can certainly use TurboActivate.

Also, I'm fairly sure Wordpress plugins must be GPL, which sort of throws the wrench in the idea of selling wordpress plugins.
