I'm doing some research about hard it is to build apps that process incoming email (think Posterous or TripIt), and exploring possible solutions.<p>If you've built or are interested in building an app that processes incoming email, I'd love to ask you some questions. Drop me an email at ajstiles@gmail.com and I'll get in touch.<p>Thanks!
Not exactly what you're asking, but I'd love to see software that:<p>_ Obtains incoming email<p>_ Parses it into something like a JSON object<p>_ Hands it off to a database or some software in configurable fashion<p>_ Explains how one configures it for a variety of common situations (email hosted mostly on Google Apps; email hosted locally; email hosted on mail server in same local network)<p>If you're interested in building something like that, I bet you'd find a lot of people who were willing to pay for it.
