Wouldn't it be easier to pay someone to point their single to your way? Or you could get an supervised acces to their computer to play around with the single? Just saying that buying a single for some minor testing is not worth it.
there are a few issues:
there also some changes on the client side - and at the moment it is not very WAN friendly - so you need a low latency and a bit bandwith - also for debugging
and cause it's still under development - to get the source from the testing client would be too easy, and i invested now nearly 800 hours of development into it, so i would prefer to keep it locally
but thanks for your reply
