I have always been dumbfounded by the fact that Google didn't try integrating wave into gmail. If they managed to make a back-end to support turning any email exchange (between people with Google accounts) into a wave at the click of a button (and without leaving the shell of the gmail interface), I have a feeling this product would have been a resounding success - the same way gchat became an instant success when integrated with gmail.
