I'm looking at it this way. We have a lot of 900 FSK and the noise floor
is already pretty bad. The power company will be rolling out smart grid
soon. Cambium showed some real-world results in a high noise floor
environment (like -50 across the band) and while the 450i worked,
throughput was no better than FSK. So the 900 450i would be a very big
investment for no performance gain.
Now, take the Runcom TVWS, which is the only viable gear right now. If
you have two adjacent channels open and can run 10MHz channel bandwidth,
you'll probably see around 20Mbps of throughput per base station. That's
5 times better than FSK or the 450i in a high noise environment.

TVWS has its place for now in low demand environments ie telemetry,
utility and industrial. As far as end user
I would be prone to make a showing in places where dial up or
satellite is the only option.
Plus with so many restrictions its about as good as 2.4 with no
interference as far as range.
Until restrictions on power and height are lifted and bit per hertz is
increased I am not impressed with the band yet.

There's a thread going on the WISP members list about this very
topic. Are you on that list? Someone said don't waste your time and
money, but wouldn't say why. So I don't have a clue, but I'd like to
put up a trial site this spring because 900 is shit.

Anyone out there had experience with it. Our is supposed to be all
on site this week. So far I haven't heard the greatest things but I
know that bad experiences tend to make the rounds in the form of
complaints more than the good experiences do so I'm trying to be
optimistic still.
