Gmail API, even just the name harkens back to 1991 era when Microsoft first bought out Consumer Softwares (http://en.wikipedia.org/wiki/Consumers_Software) and spun up it’s own mail server: Microsoft Mail for PC Networking (http://en.wikipedia.org/wiki/Microsoft_Mail). The underlying architecture was the almighty MAPI which eventually got all the corporate buyers and accounts hooked on Exchange Mail with MS Outlook clients. And the world has never been the same since. Let that be both an interesting factotum but a cautionary tale too. The first taste is ALWAYS free.
