And I just want to point out that a full /8 (worth $188,911,452.16 at the benchmark rate as set by Microsoft/NNI) is dedicated to AMPR... :-) When I was at IANA, we (where by "we" I mean Leo Vegoda :-)) looked at trying to reclaim this /8 around the same time we were recovering the /8 dedicated to X.25. The decentralized nature of administration of 44/8 made this somewhat intractable. It'll be interesting to see how this plays out in the future address markets.

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!

Me personally? No, but I have used it. IP over 9600baud serial actually isn't that bad for IRC when you're in the middle of the woods and all.
You want slow... read about winlink2000, the email/messaging system for hams and emergency response. It's PSK on HF, meant to be reliable but if you get more than 400bps you are doing GREAT! It's so slow that you can run the software on two laptops using the sound cards, and they'll talk across the room via speakers and mics no problem. It sounds kinda like robots rapping.

Nope, mostly HF (under 30mhz) gear at 300baud. Yes, you read that right.
You are running IP on this? And I though 1200 bauds half duplex was slow.
