I have no idea what you're trying to say here...  One of us is an idiot,
going by that...
Can you rephrase your last statement?

I know, I know...  I just get irritated by people expecting other people to
innovate so they can leech their ideas, and then at the same time discourage
other people from innovating...  Phools.

I know, I've looked at all the projects I could find that were already
going...  I'm dissapointed in all of them so far.

Yep.  My requirements are fairly well defined in "ubiquitous public network"
Data, anywhere, anytime, for everybody.

There's many ways to solve the problem.  Defining the problem domain like
you do lends to utilising and layering on top of existing solutions that
don't solve the problem, rather than engineering something to fundamentally
solve the problems that exist.
All I'm trying to point out is that the definition should be kept loose to
allow as much innovation to solve the fundamental problems.

Sure, but that's not where my interest lies.  I want ubiquitousness, and
existing packages don't, and are unlikely to, solve the problems in the way
I desire.

Human organisational problems don't scale well...   Having a centrally
controlled 'wireless' organistion somewhat detracts from the 'freeness'
that's possible with the peer to peer architecture...
If we went from a dozen nodes to ten thousand overnight, I seriously doubt
that organisational demand could be satisfied on a volunteer basis...
