Hi,
What can I say that hasn't been said by others before... :)
We are in contact with reliable ISPs with endpoints in various countries. They would be willing to cooperate on exits at these locations. We have not yet talked about prices.
I would say we (as in Torservers.net) are in the position to run multiple Gbit/s servers for prices at below $1/Mbit at "not your typical ISP". In theory, we would be able to fulfill the 12.5 Gbit/s alone. We're about to test a 10Gbit uplink with a Xeon behind it to find out how far we can push a single server.
That said, we should discuss and come up with a good organizational structure to reimburse people. Personally, I would only sponsor 100 Mbit/s or more (or maybe even only Gbit). I would set up a template that asks for ISP information, so we can reject too many exits at one place (say, a maximum of 1 Gbit/s or even one server per datacenter?).
Do you plan on reimbursing up front for a longer period, or only after? We would likely need the money up front at least on a monthly basis.
Another option we have that might be more convenient is to decide on the twelve/thirteen server locations up front and then ask the community to fill the slots.
Given that there are places where you get Gbit for around or less than $500, we could use the "extra money" to fund some slower locations. I would very much like to see a high-bandwidth Iceland exit. The last quote I got was 500 Euro for 200 Mbit/s (including hardware) at Advania/ThorDC.
