I'd like to user c.transmogrifier outside plone. How far is it from being plone-independent?
Actually I see very few plone-related imports and plone-only-specific code inside the trunk so that it seems feasible.
Is there any roadmap or any todo/advice list for getting this?
I've created a runner for executing transmogrifier outside of plone via a commandline tool. At the moment that runner is part of funnelbweb. You can use the funnelweb script to run your own pipelines via "funnelweb --pipeline=mypipeline.cfg" However we are in the process of migrating that code into a general module called mr.migrator. Mr.migrator will be both a commandline runner for transmogrifier pipelines and also a Plone UI to do the same.
