An "enterprise Dropbox" conversation is one that many customers will have with AeroFS. I know this from experience trying to sell this very type of product.

The challenge is that sales cycles are long and potentially high touch. One way to mitigate that is by getting sales distribution through 3rd parties. But avoid integrating with a bunch of 3rd party storage platforms unless you get commitments for leads from the vendors. In other words view integration efforts as an engineering to sales arbitrage.
