Funny, I had a native Japanese person ask me "so chris, what
do you think the next 'big thing' will be for the Internet and
Japan" just last month (and this guy is pretty tech savvy).
I didn't have an answer for him (well, actually, I do have a few
ideas, with the one or two lose marbles, rolling around in my
otherwise empty head); one thing I have no shortage of, however,
is opinions.

I suppose the tech. specs. for the NTT end of the gateways are
floating around somewhere (and I don't mean through legitimate
sources, but I'm no Otaku... or whatever the ideogram for
"Japanese cracker" is). I guess that's part of the problem with
partially closed systems... one never knows *exactly* what is
going on.
Anyway, several months ago, I had the opportunity to play around
with a Checkpoint firewall installed at an ISP. Since it was in a
region where imode has low utilization and since there were no
significant imode sites hosted by the ISP, I was able to isolate my
imode access to the ISPs content down to a specific IP address.
The behavior was weird... standard ICMP echo request/reply only
seemed to work while particular session was open and once
the content had been delivered the ICMP replies stopped (and
re-appeared randomly as the IP address was resued for a
different session). This would seem to suggest some back-end
loadbalancing.... that much is obvious.

No, but I wouldn't mind seeing a headline reading "DoCoMo imode
Conceptually Bankrupt! your phone doesn't have an IP address."
