Go to RadioShack, buy wireless FM, use it in the data center. No license.

Small problem: You can't use CB for any kind of business purpose. :( 
There's a separate business band that -can- be used for business -- you have
to get a license from the FCC to use it, but that's per-company and not
per-user.

I didn't want to come off sounding like a Nextel proponent, but it's a 
solution that's worked well here.  And yes, their convoluted two way system 
is by no means traditional, and I'm open to suggestions ;) 
Perhaps a CB with a nice oak finish would be in order.  Breaker Breaker 1-9,

we have flapping.

Loss of signal in a data center is a good point.  At a previous 
organization 
I was slaved to, we brought this up with Nextel sales people.  After about

a 
week or so they purposed a small in-line receiver for the various data 
centers, and a thin Kate Moss looking yagi for each roof. 
Actually, this should be a passive device. Various types of slotted 
waveguide/coax are made, for example in the Heliax product line. An 
antenna on the roof (directional antenna only if you're on the edge of a 
coverage area) and a slotted line through your facility will provide 
good results. Think about it for all commonly used frequencies (cellular 
and pager) that might be in use in your facility. This isn't something 
you have to get via your wireless vendor, and it doesn't need 
electronics. 
Hospitals have used such setups for years to permit doctor's pagers to 
function throughout buildings (even in basements). 

Also, I can't stress the importance of a basic two way mobile system.  We 
use the Nextel i1000+ phones for our engineering staff and NOC.  The 
internet access features on these bad boys has been VERY handy.  The 
ability 
for a NOC member to check MRTG/Openview type information and IMAP/etc. 
email 
has been beneficial. 
Something for you to think about: Your Nextel phones are NOT two-way 
radios in the traditional sense. They communicate handset to handset via 
the Nextel network (even if you're right next to each other). If you're 
in the midst of a storm or other natural disaster and your local cell 
site dies, you've got no use of those radios. Also, in the event of 
emergency, cell sites become overloaded with folks sitting in traffic 
calling people. You may find these radios least effective when you need 
them most. 
The Motorola radios other folks suggested are FM transceivers on 
business (or FRS) bands. These communicate directly from radio to radio 
(commercial gear also can use private repeaters). These are better 
choices, as they have no outside dependencies.
