Found a couple of good lagg tutorials
http://www.cyberciti.biz/faq/freebsd-network-link-aggregation-trunking/
http://wisekuma.net/linux-bsd/freebsd-lagg/

But there are a few things that I can't find so far...

Does one need a third card to reach the machine where one runs lagg?
Say I have em0 and em1, do I assign actual IPs to the cards before adding 
them to lagg or they can't have IPs of their own?

Other than lacp protocol do the other options work without having to change 
anything at the switch?

My situation is as follows:
Have two connections, 1 T1 and a cable connection.
Need to, temporarily, allow outbound traffic between both.

In a month or so the office will be moving to a new location and the 
appropriate bandwith will be allocated, but during the month or so need to 
do something about the T1 not handling the current load.

I will be getting a machine to do the lagg setup and so far ordered 2 NICs, 
but wondering if I will need a third to access the machine itself.

Any links/pointers greatly appreciated.
