To me AD Nidalee is more reliable as an assassin since dodging the spear isn't hard to do. An AP build works better outside of the action during a team fight. AD works well during close in combat and against turrets.

The AP support Nidalee players Seventy mentioned were everywhere after she was on sale using the infamous spear spam. They were more concerned about getting kills than supporting the adc.

A support Nidalee can heal/increase attack speed, poke with the spear, use traps for wards, and dive an opposing champion, escape ganks, or help get the minions away from the turret more effectively with her cougar form.)  After the laning phase is over support Nidalee can quickly become an assassin or try to fill another role.  (Note: Since every player on the team can get a free ward purchasing more may not be necessary unless ganks or a lack of MIA warnings are a problem. The new gold items are also very useful.)
