We recently wrapped up a project to develop a set of components for SEASR to do TEI analysis[1]. There are a couple of ways to call SEASR flows - you can either use ZigZag[2] to script flow construction & execution, or you can set up a flow as a web service using their web service endpoint components. We never got the latter approach to work reliably in a production environment, so YMMV.
