ah, thanks. After reading the docs again it seems obvious, but I may  
have read it too fast :)

I've just started to compile right now... Once the first BIRD instance  
is in place and I'm satisfied (and I am already way more satisfied  
than with quagga) I will deploy about 5 more instances with different  
tasks, I hope I can give you some feedback.

I've read that, but how should I say - it's a little - thin at some  
corners. Are you willing to setup a wiki for BIRD? It should be great  
to have some place for a community, I am totally willing to provide  
sample configurations and hints for our various setups. If not, I  
would create some notes on my webpage, so this can be helpful for  
others too.

thanks for the bird;
