Perhaps more of a general issue is the gaps in feature sets as we move forward, which we'd need to consider for 1-0 and identify which are obstacles we should address (e.g. operational logging, flow control mechanisms, firewalls, acls etc).
0-10 traffic does need to be supported in a 1-0 broker though, I think. Hth, Marnie
