I thought that since the viewer is Open Source, alll clients should then be Open Source or am I misunderstanding the Open Source rules?
The folks who developed Firestorm which used to be Phoenix not only made a great viewer, many of their changes ended up in the official SL viewer. That is the purpose of Open Source no?
SL itself is free to use, so why should a client be able to charge for use unless they offer something else above and beyond what you would normally get. OK maybe charge an upfront 99 cents so that tey can recoup their $25.00 for becoming an android app writer but not a recurring charge for use.
