Andy,
While you could use different systems, it gets very, very complicated
for non-digitally oriented hams. Just take some one who has never used
this stuff and really is not all that interested, but needs to use it
anyway and you will see how challenging it can be, HI.
Winlink 2000, even with WINMOR, is not going to help them much either
since it does not support the critically needed peer to peer function on
HF. Some might think you can somehow use packet radio on VHF but in our
area that might give you 15 miles in some directions, so is not very
practical. We must have NVIS for practical Section and Regional
communications.
The only sound card system that can actually do what they want on HF
really does seem to be PSKmail although I would consider it somewhat
nascent here in the U.S. at this point. I am even toying with setting up
a server here in Wisconsin, but not so much because of my central
location, but mostly for experimental use, public service potential and
certainly emergency use when the peer function is added to the Windows
version.
As you know, I have not been able to find a Linux distribution that
works adequately on my equipment. With the recent release of Ubuntu
9.04, this may be solved after all these many years. While most hams
will not consider Linux at this time, and it does have its shortcomings,
it does have some advantages and would be needed to operate a PSKmail
server station.
The really neat thing about all this is that we are coming closer to
some really good solutions for casual use and public service use of
digital technology. And anything that you expect to work during an
emergency, must be regularly used on a frequent basis to be there when
you really need it.

NBEMS is the only application that would meet your DEC's requirements,
find it within the latest implementing of FLDIGI. It contains ARQ
PSK31, ARQ MFSK16 and a few other modes. Also facilitates email
exchanges on a point to point basis with the ability to drop email off
in to the Internet. It is all free.
Then, in a few weeks time (maybe couple of months) expect Winmor to be
added to the Winkink system. Winkink currently handles files and
email via packet radio and Pactor. Pactor II and Pactor III require
expensive TNC's but Winmor will allow sound card digital applications
to connect to a server on HF. Thus, with NBEMS you have a very easy
system of point to point error correcting communication. With Winmor
and Packet in Winlink , you have the ability to do everything else.
The two combined will be about as elaborate as hams can get, ALE
systems notwithstanding.
