I'll disagree slightly. This is true if and only if what is being
proposed will supplant something that already exists. Without
getting into its merits, what Dave proposed is not something that
requires replacing IPv4 with IPvDave -- it is something built
on top of (or beside?) IPv4.
The existing IPv4 base need not throw out everything and start over,
so there is no need, a priori, to sell IPvDave to the IPv4 world and
there is no need for a deployment plan and economic rationale
and/or incentives to convince the IPv4 users to switch to IPvDave.
Then, in the fullness of time, if it turns out that IPvDave is "better"
than IPv4, and better "enough", then either
- the world will evolve towards IPvDave, putting together the
needed transition/interworking widgets using hillbilly-CS, or
- the IPv4 world will take the good parts of IPvDave and incorporate
Either way, Goodness Occurs.

See RFC1669 -- "Market Viability as a IPng Criteria"
which John Curran wrote in response to the IP:ng
call for white papers back in 1994...

Again, I'll disagree -- the sort of truly novel ideas (FedEx, The Internet, etc)
that you seem to be talking about here have pretty bad business plans
and look like they'll be gigantic flops. This is precisely because they do
not fit the existing world-view of things, so they do not fit the existing
criteria for what makes a business proposition "look good". Usually
these things end up tapping into a latent demand that was hidden not
only from the business-plan-evaluation-gurus but also the very people
who have that demand. I mean, in 1980, how many people would have
said that they absolutely need to have a portable little widget that
was a combined telephone/email-thing/picture-taker/music-player?
