- HTML documents uploaded directly to a course can be edited by a Course Coordinator (mdc priv).
- "Edit this resource" link displayed in inline menu.
- Link will switch server to course's home server if session is currently hoosted elsewehere (unless a lock is in place).
- Deep linking:
- origurl and symb args can be included in query string for switchserver call, so switched session will go to the same resource on the new server.
Work in progress.
Logging needed: changes, and by whom.

31: # browser.interface - if this is 'textual', it overrides the second parameter
