Have you made some performance tests on the fonera?

I would not expect tinc to max out the capacity of the ethernet
interface, since it consumes already too much cpu on x86.

"In July 2005, after several failed attempts to legalise software
patents in Europe, the patent establishment changed its strategy.
Instead of explicitly seeking to sanction the patentability of
software, they are now seeking to create a central European patent
court, which would establish and enforce patentability rules in their
favor, without any possibility of correction by competing courts or
democratically elected legislators."
