Failures and other exceptional cases
- ------------------------------------

_`dis23`: Client-side blocking
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Rosalind has blocked messages and calls from Romeo. However, her IM service
does not support server-side blocking, so her client must implement blocking
on the client side.

(A similar approach can be used to implement other privacy models, such as
"only allow messages from contacts on my publish list".)

Current implementation: a filter in Mission Control 4.x

Miscellaneous
- -------------

_`dis24`: multiple notification mechanisms
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

(From Frederic Peters on the mailing list)

Frederic wants to see IM messages appear as some sort of overlay when Totem
is running full-screen.

Problems:

* Having Totem, mplayer, OpenArena and every other full-screen app know about
  Telepathy messages, gnome-power-manager low-battery warnings and every other
  source of notifications doesn't really scale. Can't we solve this at the
  level of the fd.o Desktop Notification spec instead?

_`dis25`: brightness on portable devices
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

(From the Nokia Internet Tablets, but also generally applicable)

Naba's Internet tablet dims the screen when not in use. When a message
or call comes in, the screen backlight should come up to normal brightness.

Current implementation: a filter in Mission Control 4.x?

Problems: is this really just a special case of dis24_?
