I would think about the same as FM now if you look at the D/U numbers.

In today's world this comes under the category of whining.  The fact is 
that the lower VHF channels are not very useful for most advanced 
systems. It does serve a purpose for things like broadcasting. If 
someone with the cash came along and bought some of those channels, they 
could deploy any system they choose, politics be damned.
Dont think this is not already under consideration in a number of quarters.
