The release is going to happen soon :) It will be a
really devel version with some things still missing :) BTW, Wensong added
some stuff related to RS thresholds. Contact him before going
to sync with 1.0.x, 1.1.0 has some changes.

Sounds good. What does not make me happy is the bad
interaction with the routing. Currently, it is not possible
Netfilter NAT and especially IPVS to work on routers connected to
multiple ISPs and using multipath routes.
BTW, I have simple idea of moving IPVS to netlink
configuration, where we move the data in the var=value form, nothing
special. The FIB and tc are good examples. But some functions will
be needed to simplify these talks.
