The problem is that such technology isn't monetizable. I mean, you can sell the API or library or whatever that you use to interface with the inbox to people looking to develop such software, but the kind of money it would generate isn't really worth the hassle, IMHO.
Amen. Building features isn't monetizable. I wish all these companies would look at what happened to companies like LimitOne. If Google can throw a couple of developers at it and build it on their own, even if they decided to buy you out to save time you wouldn't make that much from the sale.
