That *was* that case, but Nextel/Motorola have (has) recently announced a
radio unit which will, in fact, have direct unit-to-unit short range
communications. This was due to lots of pressure from the emergency agency
types, who understood full well the dangers of requiring a network
connection before the radios would work.

(For example, if you're both in the basement and out of range of the
tower, you could *not* communicate with each other, even if you were only
a dozen feet apart).

Knowledge may be power, but communications is the key
