I think this could be a part of the solution to the 'replace email' theme by PG[1].
Since their API abstracts the email sending/receiving details away AND gives specific tags to work with [SHARE, LIST, GET, WAIT], one could for example write a TO-DO app or maybe a bug tracker that notifies and updates when a mail with a specific tag comes in.
As I understand it, the problem with building smart mail clients is that there is no standardised format that all clients will agree upon. Using this API circumvents the problem, as the mail client does not actually perform any actions. Using this API's capabilities for "smart" mail clients instead of "social" apps could be interesting.
