I agree.

I've done a number of analyses of the myExperiment workflows using
Taverna workflows to fetch the workflows from myExperiment (or from a
cache) and then run xslt or xpath in order to identify or count the
specific pattern I am looking for.  It is totally non-generic but it
works :-)  It is also Taverna-specific.

I don't know how feasible it would be to do an anlysis that could find
any workflow (Taverna or Kepler or Pipeline Pilot etc.) that matched
criteria.  The person who should know is Antoon.  I've found his new
e-mail and copied him.
