You could run a geocaching adventure, where people go find a cache in their own cities, and come back and tell each other about it, and you could leave something about your team/company in the geocache.

You could try a virtual cooking or mixology class where you hire a professional to teach the group how to cook something, or how to make cocktails (alcohol and non-alcohol). To pull it off, you can either send people a shopping list the week before the event (easier, probably cheaper), or ship/deliver the ingredients to their homes ahead of time (harder, probably more expensive).
