eamonn,
I'm going to have to report you to the unAustralian Activities Commission for this comment of yours:
"And I'm living in Oz. (Vegemite sucks)"
Otherwise, I'd be interested to hear your thoughts on wireless infrastructure if you have a chance. You're right that the Wave conversation seems circular at times. But "this time it's different!" ;-)
Actually, I believe it is. The zit's about to pop, with Seagate's drives, and Endpoint Enforcer about to be released. If Wave ever delivers, it will be now, in my view.
