Maria, thanks for your review and feedback !
This new Community Edition will evolve and improve in the next weeks and some simple options may be added. Consider it a work-in-progress. :) That's all about Kaizen (continuous improvement philsophy).
Concerning Imprudence, it is indeed the only viewer (with Kokua perhaps ?) that is fully GPLv2 thus allowing redistribution along side the Community Edition. If there's a MOAP+Mesh viewer that is 100% open source then we could replace Imprudence.
Hypergrid functionnality is configurable manually (INI files, ports forwarding...), but all the magic of New World Studio (automatic network and firewall configuration) goes into the paid version which will directly fuel the project on the long term. I also already got requests for customized New World Studio distributions/installers with per project logo etc... I deeply think that would help widespread OpenSim adoption, especially in schools and universities.
