[hobbit] xymon ready to replace bb?

[Husemann, Harald]

Hi Martin,

I can of course write a doc about our setup to share my experiences. As 
I saw, there was a bit of a discussion about the right place for it, so, 
question to the list:
Where shall I upload it? Or shall I send it directly to the list, and 
someone (TJ?) picks it + includes it?
