The trick, I think, is to make a better shared space for a remote/local team than the physically shared space they already have. A space that is just as fluid, fun, and useful as a physical space and available anytime, everywhere is more compelling because it affords its occupants (aka team members) more hours in their day (no commuting, flexible hours) and permits all sorts of non-traditional work locations (coffee shops, trains, sofas at home, a summer trip to Europe).
