We're dealing with this every day, outside of RIPE meetings.

The RIPE meeting network is not a playground or experimental environment, 
but is there for the primary purpose that people who attend RIPE meetings 
can be able to contact their home networks in case something urgently 
need to be done there.  With as little extra pain as possible.

Having test networks in addition (!) to that is good.
