Thank you, Steve. Your point is very real, and the historic
'solution' has been for the government (FCC) to impose regulatory
handcuffs on the market-based arbitration of that tension. This has
the practical effect of total regulatory favor of the legacy use over
the exploration of new ideas.

New ideas not only have to overcome regulatory hindrance to
feasibility trial (STA's, etc.) but once on the air must fit into a
regulatory mishmash of allocation buckets already dominated by old
legacy uses. This is the ultimate irony in the only radio service
chartered to "advance the state of the radio art".
