[hobbit] xymon ready to replace bb?

[Martin Flemming]

Grmph,

you're right,  one place for all is the best solution ..

Me for myself,

  i switch from side to side ... and would prefer on central Side, too !

... by the way, the wiki-side from TJ is very well and comprehensive ...

there will be a lot of things to merge into the "offical" Xymonton ...
