Arvados

Use something like http://markitup.jaysalvat.com/examples/textile/ (GPL) to render descriptions as textile on the client side. Hopefully a fairly simple matter:

• Fire markitup's trigger on document load and after x-editable saves new content
• Use the appropriate x-editable features so it doesn't do anything silly like pop up a textarea with rendered html in it.

Add a textile extension to make it easy to link to Arvados objects as easily as URLs (e.g., "This project":zzzzz-j7d0g-asdfasdfasdfasd would link to the appropriate Project page on the current Workbench site).
