I planed to add support to CARP in future release, I exchanged with OpenBSD 
author in the past asking to port it to linux. Since CARP is quite similar to 
VRRP the work can be done very quickly, but as I asked to OpenBSD hackers to 
port it quickly I need a small specs on differences between VRRP and CARP... no 
news...

Anyway the merge of Jacob Rief THC design is high priority in my devel list. 
will do this in a near futur....

If you only need a small throught put then userland is enought, I would said, 
is the best IMHO. To handle around 20pps is the worst case... :)

If you got some specs please forward then :)
