Re: INDIRECT and real-time question

Sounds like your goal would be to create a 'RealTime monitor range'
and just blit the data back at regular intervals.  Implementation is
msotly trivial with 2 wrinkles.  How to handle queued updates while
editing, and the implications for undo/redo.

    - Do we want recalcs even while editing ?  The simplest solution
      is to say yes.  but I frankly have no idea if the system will
      support it.

    - undo assumes that it is the only thing changing content.  So
      if you do an undoable operation in a real time cell then undo
      & redo _after_ an update the undo mechanism will restore the
      updated value, not the original typing.

Merging in new ui is actually partially supported (bonobo build only
for now).  Have a look in the uihello plugin for an example.
