ActiveSync and SyncML are completely separate protocols. Not all  
devices support ActiveSync (most notable blackberry devices) and not  
all devices support SyncML, so we do still need to support both.

As far as ActiveSync goes, no.  There is no support for child tasks in  
the AS protocol. There are also quite a few clients (iPhone included)  
that have NO support for tasks whatsoever.
