I thought of that, or of using a while(1) loop in a shell script. The  
problem with that is the restart time. I don't know how long it would  
take, probably less than a second, but I'm concerned it might be more  
time than we can afford. I'll try it out, its a temporary solution  
anyway, until I can write my own application.

The problem with sredird and RFC 2217 is that it is TCP based, and I  
need to use UDP, at least for now.
