[Soekris] Industrial control application

[Karl Fife]

We have a dos-based industrial control application that we want to migrate 
from a 'real' dos workstation to something like a network-attached virtual 
dos workstation.  One objective is to make it administrable via browser from 
anywhere on the network rather than by physically walking up to its console. 
We would like to have the DOS instance hosted on a high-availability fanless 
solid state host like the NET5501's we use elsewhere.   The only industrial 
control I/O required is a serial port.

Has anyone done or seen anything like this on Soekris?  Any projects I 
should be looking at?  Is Soekris the wrong fit?  I've looked at Mini-ITX 
type solutions.   I considered building up a 'headed' ITX unit with a 
wear-leveling SLC SDD, and simply sticking a KVMoIP device to it.  Not 
exactly elegant.  We're not particularly cost sensitive.  There's an 
important industrial process riding on this two-bit DOS pc.

Ideas?  Experiences?
Thanks!
