-TODO items for NetworkManager
------------------------------
 
-Any of these items are of course fair game for anyone, patches are greatly
-welcome.  It also serves as a "what still needs to be done" list.
-
-
-- Access Point link checking thresholds
-
-Wireless link checking could be enhanced to check the signal strength of an
-access point and switch if the current access point a wireless card is
-associated with has dropped below say, 20%.
-
-
-- Support 40/64 bit passphrases
-
-Allow user to enter passphrases and convert them to 40/64 bit WEP keys on the
-fly.  Unfortunately, the algorithm for 40/64 bit passphrases is kind of messy.
-
-
-- Proper PPP support
-
-Provide integrated and proper PPP support, replacing the current per-distro
-code.  Seamlessly communicate with pppd, manage the dial up profiles ourselves,
-and so on.
