Yes, yes they can

no, no they can't.

however:

"If a source you control would deal noncombat damage to an opponent, you may have that source deal that damage to a planeswalker that opponent controls instead. This is a redirection effect: you choose whether to redirect the damage as the redirection effect is applied, and it's subject to the normal rules for ordering replacement effects. The player affected by the damage chooses the order in which to apply such effects, but the controller of the source of the damage chooses whether the damage is redirected. Note that this redirection can't be applied to combat damage."

so while the damage can still be applied to the planeswalker there's a crucial difference in that you still have to target the player.

^^^ The distinction IS important. If the player has shroud his planeswalkers are protected from player->planeswalker damage redirection but not from O-rings.

that's fair, i assumed damage spells instead of all spells, my mistake
