As a quick plug, you can sign your incorporation docs with HelloSign (http://www.hellosign.com) and fax Delaware with HelloFax (http://www.hellofax.com).

In my case, I used the InCorp service to file my DE docs since I needed an expedited service and they could walk the documents over on my behalf. In the past, I did that portion myself.
Thanks for building a great service and down with the fax machines!
