University of Arkansas combined Voice over IP (VoIP) phone technology with 802.11 -- the wireless protocol, in single devices. And, they reduced their monthly service fees from $530K to $6K, a cost savings of $6M per year. That ought to cover any hardware overhead issues.
Imagine, you can carry your phone like it's cellular, and it costs less too, by a lot.
You've gotta love those revolutionary technologies.
