Very nice feature :)

Though using todays CVS (head revision for radiusd, checked out about 3 
hours) , I still get Unknown type "client_balance".
Also it doesn't let me put multiple servers in a server pool, and dies 
on runtime with

/usr/local/freeradius-cvs060407/etc/raddb/radiusd.conf[147]: Ignoring 
duplicate home server jrs1_auth.

Oh typo on my part, though yes might be good to check all the servers in 
the server pool are of the same type,
and that accounting pools are not used for acct_pool declarations in 
realms and likewise for auth.

Yes, just realised that :)

Yes.
