If you are wondering what is cooking in the various tracks at Tech Ed this year (and some have been) then you might want to check out some of these posts by some of the track owners:

Jeff Alexander - Windows Server Track Planning
Rocky Heckman - Security Track Planning
Johann Kruse - Unified Communications Track Planning
Nigel Watson - Architecture Track Planning
Alistair Speirs - Office System Track Planning

As usual we are organising the New Zealand event in conjunction with Microsoft Australia, and the Australians have put together a page to allow attendees of either the New Zealand or the Australian event to contact the track owners and ask any specific questions via IM. 

So if there is something specific you want to see, send an IM via the Tech Ed AU track page.
