Interesting… I wasn't aware of your work at all, although we had a  
brief exchange on OpenERP's mailing-list if I recall correctly.

Your builbot openerp setup seems to go much deeper and be more  
advanced than mine, which is merely a configurator (http://pypi.python.org/packages/anybox.buildbot.openerp 
), but I'm not sure they share exactly the same goals.
I'd certainly be glad to discuss this elsewhere with you, as this  
probably will be quite off-topic here.

Funnily enough, the first functional testing case I was thinking of in  
this port reservation thread is not related to OpenERP (later ones  
surely will).
