Fellow Adobian Jon Perera has posted an article entitled Enabling Friction Free Business - Adobe's eSignature Roadmap. He starts by noting that 90% of contracts in North America are not signed electronically (a rather sad stat, IMHO). He then states that 50 million agreements have been signed on the Adobe EchoSign platform, and goes on to explain the roadmap for these products. While a little more marketingy than I'd like, this one is an interesting read.
