title: Sharepoint 2010: Does free "Foundation" version is enough for document workflow tasks
body: <p>I wonder if Sharepoint-2010 Foundation version meets requirements of a company I work for: </p>
  
  <ul>
  <li>Free </li>
  <li>Proven extensible document workflow system for Windows</li>
  <li>Able to store gigabytes of document scans inside (Does Sql-Server Express appropriate for that, how does Sharepoint store images?) </li>
  <li>Allows to use electronic signatures</li>
  <li>Notification subsystem, filters (I guess Sharepoint is ok here) </li>
  </ul>
