Peter, leaving aside the issue of FreeBSD limited broadcast, have you 
considered ZeroConf, and in particular the IPv4 Link-Level Addressing 
portion of it to meet your basic "get the boxes addressed" requirement?

http://www.zeroconf.org/

I don't have any experience with the lagg device yet, so I don't know if 
that presents specific issues wrt ipv4ll code.
