Even the GPL doesn't deny actually selling your application - as long as you provide GPL'ed source code to every purchaser. So, in case of GPL, it's not much different than any other paid program - you sell it, and hope that people respect you and buy it, instead of getting "pirated" copy.

The only difference here would be that you hope that users respect you and buy it, instead of compiling from source posted "somewhere", released by prior purchaser.

IMO, compiling from source require (nowadays) even ma little more effort than downloading "pirated", "cracked" version and running it, so I would say GPL'ed payware is even better for distributor. Especially, considering the "target" Maemo user-base - I guess that 99,99% people here would preffer to support and respect developer like you and buy your piece of code, than get it from 3th hand.
