No, IMHO. Most broadband operators don't insert firewalls inline in
front of their subscribers, and wireless broadband is no different.
The infrastructure itself must be protected via iACLs, the various
vendor-specific control-plane protection mechanisms, and so forth, but
inserting additional state in the middle of everything doesn't buy
anything, and introduces additional constraints and concerns.
