Send Docs for Signature from DropBox, Box, + Other Apps on your iPad or iPhone With "Open In ... EchoSign"

EchoSign's iPad/iPhone app utilitzes the iOS "Open In" functionality to allow you to open a document from most other applications that have documents and contracts in them -- including DropBox and Box(.net) and others -- and send them out for signature via EchoSign's iOS app in one click.

How?  Just install the EchoSign iPad/iPhone app from the AppStore.  Then hit "Open In" in any app that supports it, and EchoSign will be a pre-installed option.   It will then open up, automatically attached, in the EchoSign iPad/iPhone app.
