We recently had a webcast at SBUG where Hans Hanston from Agile Point demonstrated a little about their BPM product and how it could be used to create a composited solution integrating sharepoint and SAP.

Note one of the really interesting bits of the demo I thought was the upgrade and versioning of a process running in AgilePoints BPM platform. It was interesting to see how you could easily visualise the differences and opt to roll back in process instances to an earlier state so they could take advantage of the upgrade.
