Space on other mirrors do need enough disk space,
atm it really should stay under 20G, not breaking current 
agreements.

And, the other question would what more mirror systems over time?

The is still possibility at Internet Systems Consortium (ISC) to mirror
a 2G subset. Here is we should decide quick, to use the moment of
opportinuty.  (third time I mention it)

My idea would to get on a fair amount of mirror systems, and find a way 
the balance the load.

2ct,
