More ramblings from the annoying route engine guy...

So, I've been slowly making progress getting my route schema working 
within LWIP.  This is not the way to learn C.  In any case, after 
chatting on #dragonflybsd I found out that many people are 
interested in something that rolls vrrp/carp/etc functionality in 
with loadbalancing, so loosing an interface doesn't drop a box, etc. 
I just happen to have been spending the last few days pounding on 
Extreme's and wonder if their schema could be of use.

Extreme's are an entirely virtual interface driven system.  For 
simplicity they call their interface's vlans, although they have 
nothing to 802.1q.  IP interfaces are defined by individual vlans. 
These vlans are then bound to one or more physical interfaces.  This 
lets you literally bind say, to 4 gigabit ports.  It 
might be cpu intensive, but instead of layering on carp/vrrp could 
this sort of schema work and allow even greater flexibility?
