Ham Radio Networking (was Re: Rogers Canada using 7.0.0.0/8 for internal address space)

Used to run IP over AX.25 using KA9Q JNOS back in the day.  HF at 300
baud simplex / half-duplex and VHF 144 Mhz at 1200 with similar
characteristics.  I bought some 9600 baud gear at one point but never
got it all put together before moving on to the regular internet and
(somewhat unfortunately) not really looking back.  I remember
transferring some uuencoded gifs via smtp...  a couple of days later,
if you were lucky, it would complete.  I learned about how protocols
communicate watching packet traces in KA9Q JNOS when I was about 14
years old.  It was really easy when there were guaranteed to be
multiple seconds between packets.  I remember being 14 and feeling
pretty suave when I figured out how to telnet into an SMTP server to
send mail...  of course that is old hat but still good common
troubleshooting these days!
