Workflow sharing features in Kepler

Several projects seem to be working on infrastructure for workflow sharing in Kepler.  This interest group is an attempt to bring these people together to find common ground on how to build infrastructure for Kepler.  I thought I would list several known projects to initiate the discussions, and where possible we've linked in design documents to the workflow sharing interest group page.

• REAP: Developing mechanisms for packaging workflow runs and their run history in KAR files, building GUIs to share these through the Kepler Workflow Repository (http://library.kepler-project.org), and building GUI tools for reporting and run management that help manage outputs in a presentable manner.
• myExperiment: a general-purpose workflow repository.  We may be able to expose Kepler KAR workflows here with modest changes.
• CAMERA: rumored to be working on workflow sharing via the web  -- hopefull y more details to follow
• Hydrant: web-based portal for uploading and sharing workflows, and also can execute workflows

I'm sure there are others.  It would be great to see current plans for all of these projects and others posted to the Workflow Sharing Interest Group.
