I think what new condos within the Bixi 'bikeshed' should do is offer a free 1 year Bixi membership as part of the condo purchase. If those buyers don't use it, the condo companies are still paying into Bixi, and if they do use it, then Bixi gets more ridership and more exposure. The condo companies also get to market themselves with that 'urban trendiness' that they love so much. Because really, what's it to them to throw in an $80 membership (I think that's what it is) on a $400,000 condo purchase? It's peanuts to them.
I personally think it's a win-win-win.
