Just last Thursday they made another release so it certainly doesn't
look dead. I've been following the project for awhile now to see where
it's going to go. The lack of FreeBSD support isn't great but I doubt
it's going to happen until someone steps up and makes it so. The same is
likely true for VLAN support. So far it's primarily been a proof of
concept from what I can tell and could be molded into any number of
different applications with the appropriate support.
Considering all high performance routing platforms separate the
management and routing/switching into two (or more) different hardware
sections it wouldn't surprise me at all to see this as the only real
option to get some serious routing and firewalling performance out of
i386/amd64 type servers. Throwing faster and faster cpus at it is only
going to get you so far (re: opteron 2212 vs 2222). Even so, 1.1Mpps is
a considerable rate.
