Absolutely. NAT is too fragile/expensive/non-performant for these setups. CGN boxes are too new to be economically borrowed/rented, maybe one day it will be possible, but for now we can still get the address space required (Timespan issues notwithstanding)

I suggest either getting a L2 circuit or else IPIP/GRE tunnel to somewhere with a functioning internet market. It is far preferable to tunnel than it is to have session state in the network.

I've been part of the team deploying networking to various leafy parts of the Netherlands (e.g. HAR2009), ex-soviet airbases (CCC Camp), a park in Milton Keynes, UK (EMF2012). With some thought and creative planning it is possible to bring in a useful uplink in the 300M-10G+ range. [I'm not sure I remember those DS3s and OC3s that other posters are talking about, something these days used only in developing countries i thought ;-)]

As a network engineer, these events are a great way to meet people with different experience, talk to eager young folk, do things in a different way and generally have a reset on your professional life. You might even get some sun too :-)
