Right there I think we already have the beginnings of a problem, with 
your term of "system"

This implies a formal system, I was speaking of an INFORMAL "system".

Ideally the hostmaster of ARIN should be able to send an e-mail to the
hostmaster of, for example, RIPE and say  "I noticed that we got block
W.X.Y.Z/24 given back to us from Wonkulating Gronkulators, and I
also noticed that your managing the 2 adjacent /24's that surround it
and it seems to make more sense for you to take W.X.Y.Z/24 so why
don't you take it over?"

In short they should be able to just do these things without having to
go through all the rackafratz of handing it back to IANA for IANA to
hand back out to RIPE.

Or am I assuming too much about the hostmasters of the RIR's?  I had
always thought the ARIN hostmaster we worked with seemed to be a
pretty competent fellow, but maybe I'm wrong and we need Grandma Iana
to supervise this?

So what?  The point here is to get the IPv4 in service, right, isn't
that the whole point of reclamation?  Who cares if the people that
use it are in North America or elsewhere?  The sooner we get the
bits and pieces assigned out the sooner all the scrap IPv4 will
be put in service and then people won't have an excuse any longer
to think that there really is some sort of future with IPv4 and
will have to get serious about IPv6.

"land-grabs" the very word assumes that IPv4 property will have
indefinite future value.

Anyone taking IPv4 right now is a speculator, pure and simple.  When
an ISP gets IPv4 they are doing so because they are gambling that
they will need it for the future.  Years ago that was a very safe bet,
today with IPv4 running out, it is a question of how many more years
are you going to need it.

If I could tell you that in exactly 2 years, IPv4 will be regarded as
worthless because everyone will be on IPv6, would you spend the time now
to apply for IPv4?  What if I told you that in 6 months it will be
worthless?  We all agree it's going to be worthless someday, the 
question is when.

The situation is akin to the community that has a old bridge in the 
middle of it that's falling apart.  The community knows that sooner or
later the bridge will fall, but they spend lots of time debating how
much more time they have left before the bridge collapses.  Then one
day the bridge unexpectedly does collapse, and everyone then says
"gee, I was sure it was going to collapse but I didn't think it would
be TODAY!!!"
