That's a damned goo idea F1k, how do I set up a node? this thing is up 24/7!
My KOIN node runs on IP 82.157.202.78
The port for KOIN is 41338
Make the wallet you use for the KOIN network accept connection from the outside world on port 41338 and you're good to go.
I think I started my node around July 1st and I have not received any kind of complaints. I think this should help exchanges list the coin, as clearly there is no issue with KOIN.
