Yes, I remember there is some unconventional applications. It's good to 
know you have succeed to get some 'return of investment' around this 
project.

Very good news, congratulations !

I was involved in a similar project (1995-1999 not achieved, change of 
internal priorities in a company I worked) where I insist to use 
standard email client. I'm very pleased to see I am not the only one to 
believe that standard tools are friendly for standard users.

This is exactly the same way I proceed to design the system, with a 
small web server embedded for parameters settings. All of this result in 
a simple service or daemon hidden for the PC end user.

Some fine side effect : 1) The software was instantly portable in any 
platform who supports Ada language (almost does) and have a std email & 
web clients. 2) The "HF server" could stay in text mode, serving a wifi 
or ethernet intranet.

The major difference was around the modem used : it was PTC-III, a 
proprietary solution, good performances, but your work and design is far 
more efficient & clever : you can control everything in a software only 
design.

At first glance not too difficult , full of trick in real world, 
especially if you use SMPTS and POP3S...

Well... all this is really exciting.

About special versions...

What is the major techs. diffs. between the PC-ALE I knew and the 
special MARS release (reserved to MARS operators) ?

Hope I may, one day, contact you on air, thanks to PC-ALE !
