We are using JIRA to organise our stories. It would be nice to integrate the story files directly from JIRA, so you don't have to write them twice. At this moment we write the acceptance criteria for a story in JIRA and we copy them into our projects.
My idea is to
-extend the LoadFromUrl class to add the functionality to log into a page (like for google docs). Something like LoadFromSecuredUrl, LoadFromJira
-then write a parser that extracts the fields from a story in JIRA as plain text like you propose it here http://jbehave.org/reference/stable/locating-stories.html
