If a branch of the government is going to spend time and resources clarifying things like this, they will most likely follow through with some enforcement.
They'll probably pick off a few of the guys that run the big networks. It'll be big fines and a slam dunk on the challenge if they are fought in court with how clearly things are spelled out now.
For the last year this topic has really been boiling, yet people said "oh it will take years, maybe never, for the FCC to clarify linking repeaters". Under a year for clarification tells me that they've gotten so many complaints that they can't sweep them under the rug anymore. If this doesn't work they'll nail a couple guys to the wall to set an example so they (FCC) can quit spending time on GMRS.
