I think the question you have to ask here is this: does your plugin require
arcpy to function properly (whether via a bridge or not)? If it doesn't
work without it, then its a derivative work*... and since it obviously
doesn't work without pyqgis, which is gpl, it can't legally be released as
* I'm not a lawyer, so take what I say with a grain of salt... blah blah...
