It is not a fact that IPIP is difficult. It is either
easy (if your ISP
router will forward IPIP or at least allow it through a DMZ) or impossible.
This isn't the fault of ipip, it's the poor service of the provider in
this case however for decades, as ISPs have put up hurdles, we as hams
and inventors have found ways around what ISPs to do stop our routing.
> routing IP datagrams over radio links
This isn't the optimum way to do IP over ax.25 based radio links.
Datagram is like UDP - lacks error correction. Case in point would be
VoIP/SIP in a weak area. Missed frames stay missed and broken in a
stream of data. Things get grunged.

... and the ham doesn't gain knowledge but continues to be an
application user, then when something happens due to changes by their
ISP they don't know how to properly debug it because they haven't gained
the skills needed to debug networking.
The system we use has dynamic routing by default since IP on VHF/UHF is
encapsulated under ax.25 very similar as if we were able to have BGP
based border routers between us. If an ax25 path breaks, and an
alternate path exists the IP based socket stays open and connected at
both ends. We're also running a higher MTU than a netrom (MTU of 192
bytes) based system does without fragmentation.
This is quite impossible with the software solution previously
mentioned.
