I have noticed a lot of viewers Firestorm, Teapot, Kokua, Imprudence, are using "hop://" which ArminWeatherWax has made code available for how to add it, if i am not mistaken he developed this protocol... I might be wrong... Anyways here is how it works:
hop://<grid login uri>/<region name>/<x>/<y>/<z>
So an example of one is:
hop://login.cyberwrld.net:8002/Welcome/128/128/22I hope you can think about adding this functionality.
