Hello,
I have experience working at ISPs supporting dedicated servers and am interested in operating a sponsored relay.
Potential issues I see:
# A true 100mb network connection is going to be expensive. Often a 24 port edge switch has just one 100mb uplink port.
# As an operator, I might want an LLC to protect me from personal liability in the USA.
# Ideally an ISP outside the USA would be used so the server is in a different legal jurisdiction than the operator. This would make payment and communication more difficult.
At this time I imagine a server with an encrypted file system and long term log retention disabled. Reasonably hardened OS, but nothing too exotic. I think $100 a month above other costs would be fair. But I do not know how much attention a node would require once it was set up. If it requires a lot of time, more compensation would be in order.
I am not looking to make a lot of money doing this, but I can not do it gratis.
Cheers,
John
