I've used the Digi devices for Clearwire site OOB and in many retail
situations where they are use for backup connection and for when the wire
line hasn't been delivered yet.  They do come with a static IP address if
you request (and pay?) for it. They can come from the shared mobile IP
range (RFC 2002) so that you can keep the static IP as you move between
tower sites.  You can also get them "piped" right in to your net via a VPN,
although I suspect that is only affordable for a very large install base.

Real world 3G bandwidth is about 1Mb/s down and 300Kb/s down.  RTT (ping)
is around 185ms to a local IXP (which kinda sucks for terminal support, but
still better than a POTS modem.)
