Ignorant question - but I assume this is not something that those of us stuck in "Enterprise IT / Big Corpo" can easily benefit from?

* I don't see Outlook/Exchange as part of Integrations (let alone more fun stuff like Lotus Notes etc :P)

* I assume it'd be essentially impossible to open ports, gain permission, pass security task list, bribe system administrators and security control officers etc for individual to integrate this into their enterprise email system
