Oh, many of us WANT change...but not at the expense of the -RADIO-
portion of the hobby. Internet =! Radio. That fact has been pointed out
numerous times by those who design, maintain and operate the existing
packet radio network.

Do amateur radio operators need a high-speed packet-radio
infrastructure? Probably. Moreover, one can be built to exclusively
utilize RF as its transport mechanism; the Internet need not enter into
the picture whatsoever.

Once it's built and in place, the question arises: What to do with this
network? 10MBPS or higher would give excellent throughput for
high-volume traffic forwarding...which is about all you're going to be
able to -legally- do with it. (See previous remarks copyrighted
software, et al. The sentiment of most SysOps involved will be: It
ain't passing through my station. Period. ANY file other than
plaintext, that is...and rightly so.)

" That's were hams would have to be the network both on the radio, and
on
the internet from scratch. again the only ones allowed to use the
software and the network would be the amateur radio operators."

Again - how will you control access to this system? There's also the
matter of network security - put such a "node" on the Internet and I
guarantee that it will be hacked as soon a vulnerability with the
system is found.

"The filter system which would block these "large" would be in the
software and would be unchangable. "

Would you filter based on size alone? Actual content (type) of the
files? MD5 hash? I (and every other comptuer-savvy individual on the
planet) can easily bypass any of these schemes by manipulating the
files in certain ways...if the filtering is done via database, it would
be enormous and a true PITA to keep up to date. Thus, it would be
dropped in short order.

Looking at the whole proposal from a great height, it closely resembles
the existing AirMail/SailMail PACTOR systems...which operate under an
entirely different set of rules and regulations than does amateur radio.
