[FedCom] Federal User's Nextel/Sprint IDEN?

[Ken]

Recently I was looking at the new Sprint/Nextel site (Sprint bought Nextel). 
I noted that from a federal prospective that the following contracts were 
available in the past:

*General Service Administration (schedule) -- Basically any federal/military 
department can use.
*US Navy
*Federal Bureau of Investigation (blank purchase agreement)
*Department of Treasury (blank purchase agreement)
*DSSW ?

Some agencies'  traffic on normal fed radio frequencies seems to be limited 
basically to check in's/check's out, so I'd assume that the agencies are 
using some sort of cellular/pcs services.....

I think that Nextel's introduction last year of  "direct talk" (off network 
simplex unit/unit comms) was probably due to pressure from government 
agencies that wanted to have a simple method of communicating if they 
weren't within range of a nextel sites.

IDEN is currently not monitorable with consumer grade scanners....  Does 
anyone have an idea as to which federal agencies currently are heavy users 
of NEXTEL's IDEN service?
