Sync with Outlook/Google
My main reason for Outlook integration would be the use of exchange in the backend.
Or also make a MS Exchange integration
Of course, keeping the hierarchy order of items.
I've been using ecco since 1996 and I'm now using both google calendar, toodledo.com, DTG GTD android app as they all sync between my laptop and my android smartphone.
I have 12MB of information on contacts and freeform info in my ecco database that I consult frequently...although I don't use the calendar and todo capabilities anymore in ecco.
Syncing calendar with Google or Outlook is the gateway to use InfoQube with Android phones. Yes!
