Tell you what ... I would have to go read the code myself to document 
it :-)

It was written quite some time ago because I was having severe 
performance issues with RRD file updates - the disks just couldn't keep 
up with the load. So xymond_channel got an addition that let it send 
updates to a worker module on another server, and to find out where 
stuff was I re-invented DNS in xymond_locator.

Well, kind of at least ...

It isn't my favourite piece of code, because it adds a fair bit of 
complexity to the channel/worker communications.

Indeed!

Hmmm ... yes, I should document this properly. man-page, I guess.
