That's a fundamental problem. Even with static routing you cannot hope
to have something usable for basic TCP transfers.

Forget about hoping over the same frequency.

Protocols that use metrics more intelligent then packet-loss based
should be able to detect fast links.

Babel is not able to make the difference between a 1G and 100M
ethernet link for example.

The same problem when your radio changes from 5M to 11M.

And that's probably the case for other routing protocols as well.

"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."
