Well, actually what they need to do is implement the equivalent of my
software flow control which will allow you to feed data through the
radio with no buffer problems as long as the radio doesn't melt.  Based
on their prior issues with Kenwood TNCs, however, this isn't the way
they normally attack problems :)

Actually, D-RATS provides an abstracted TCP tunnel transport that would
let you treat it like an SMTP server, which is even less work for them
(and should work as-is, unless their software sucks more than I expect).

Don't get me started on that.  I only wish I was visible enough for them
to hate me :)

It seems to be something that people want, which is my reason for
considering it.  The VHF side of Winlink seems rather useless to me, to
be honest.  Email in D-RATS doesn't make too much more sense, except
that it would be open, cross-platform, and cross-hardware.

And it also happens to be the #1 most expensive[1] way to get 160
bytes of data from one device to the other.  Hard to call that much
of a success, but...point taken :)

AX.25 is ancient, bloated, and less relevant today than ever.  WinLink
(and lots of other stuff) uses the FBB forwarding protocol, which is
beyond archaic and limited.  TCP/IP is quite relevant, but doesn't lend
itself very well to mesh networks and brings a fair bit of overhead to a
1200 baud half duplex link.  What to do?
