Also, in our world it is a bit of a nuisance that there is no way to incorporate some form of dynamically determined link quality in the routing decision. Links are either up or down. But for this proposed use (replacement of the IPIP mesh) that is not a problem, it mainly affects the use of BGP on the radio links in our network.
As far as we are thinking about possible evolutions, we can also add new criteria. Ability to change link "weight" according to link quality (or other parameters) may be an intesring thing. Marketing guys used to call that "Software Defined Network" in some commercial solutions ;-)
Of course, the routing protocol used on the Internet transport side is not necessarly the same as the one used on radio links. But if we can find a protocol that does both, maybe it will make things easier...
I don't know if BGP has some "weight" parameter. OSPF has. It can not change the weight dynamically, but it's possible to change that weight by an external script. That's nice, and that's the reason why we choose OSPF for our "internal" network.
