GigaOm has reported on a reported another try at the public markets by Craig McCaw backed Clearwire.  A Wimax based wireless broadband provider.  Well they are correct in the article about building a national wireless broaband network being expensive to rollout.  To date they have had $191 million dollar loss.  I do believe if anyone can do it Craig can.  To quote "Field of Dreams" : "If you build it, they will come".  Let's hope so.
