The licenses aren't a formality. When there is an interference complaint,
the licensed user gets to see the unlicensed user issued a "Notice of
Apparent Liability." If they don't pay it, the Department of Justice takes
them to court and sees it removed from their hide.
Churches and trade show hawkers can use wireless mics limited to 100 mw, and
use unused FM radio channels. (You actually don't know what frequencies
they use by listening.)
There are several manufacturers that have marketed -- and sold to unlicensed
users -- 950 mHz wireless microphones. Companies like "Shure" and
"Sennheiser" and less well-known brands. These frequencies are the
exclusive province of auxiliary links for FM radio stations (their only
exclusive band). There is an argument that the vendors are moving the 700
mHz users of which you speak to these previously allocated channels.
You can expect the FCC to issue significant fines -- multiple millions of
dollars aren't out of the question -- to the vendors, users and
manufacturers/importers in the next phase.
Just a formality, of course.

Wireless mikes are used by MANY groups, not just broadcasters. In
theory you need a license to use them, but in reality most of these
devices are never registered with the FCC. Among the groups using
them:
Churches
Live performance theaters
Independent producers and videographers
Trade show hawkers
I've seen estimates that far less than half of these devices are
operated with proper license. NOt that it matters, as the license is
a formality. The critical issue is that local broadcasters typically
police the channels being used and publish database of the channels
that should be used in each market.
And then there is the other reality - there is a large installed base
of wireless mikes that use frequencies in the recovered 700 MHz
spectrum. These "licensed" devices will not be able to use these
frequencies after the analog shut-off. Or more accurately, users of
these mikes will likely interfere with the new users of this spectrum.
