What is a "REAPER-only, non-commercial use" license?

The REAPER-only license will only show as registered when used within REAPER ( http://www.reaper.fm/ a product of Cockos, Inc.)...the plugins will WORK in other hosts, they just won't be registered. An additional caveat in regards to this license is that it is only for non-commercial use. Use common sense...if you're making money or trying to make money using the plugins, it's probably commercial use. Using them in a commercial FACILITY (studio) is commercial use.
This license is specifically for hobbyists that are making music at home with REAPER for their own enjoyment...as simple as that. All others should purchase an "All hosts, commercial use" license.
