So what's your take on the earlier example?
I agree with the way Artoomis has handled it above.
The Rogue makes one Hide check (with movement modifiers) as he creeps up on the Goblins and settles down behind the bush.
Each of the the three Goblins has it's own individual chance to Spot the Rogue, so three Spot checks are made opposing the Rogue's Hide check.
(Some DM judgement might be needed here. If the three Goblins are standing in a circle talking, it's likely at least one of them isn't even looking in the Rogue's direction. So I might only ask for two checks. I might even give the -5 "spotter distracted" modifier if the Goblins really aren't paying attention to anything but each other.)
Once the Rogue has successfully hidden behind the bush, no more Hide checks are needed unless he moves. (Or if for some reason the Goblins move closer to his hiding spot, or something makes them suspicious and they start looking around more carefully.) But if the situation stays the same, no more Hide checks are needed.
Once the Hobgoblin appears, he gets his own chance to spot the Rogue. Like Artoomis says, there's some DM judgement involved.
For instance, If the Hobgoblin came out of a tent that's directly behind the Goblins (the same line of sight) I'd use the already established Hide check. But if the Hobgoblin appeared from another direction, I'd probably have the Rogue make a new Hide check vs. the Hobgoblin's Spot. (The Rogue sees the Hobgoblin emerge from the tent, and has to quickly adjust his position in an attempt to avoid being seen.)
Finally, as the Rogue decides he's heard enough and starts to move away, there would be a final Hide check with movement modifers as he sneaks off. If the three Goblins are all looking at the Hobgoblin (who is screaming at them for talking while on sentry duty) there might only be the distracted Hobgoblin's Spot check to worry about as the Rogue slips away.
And Artoomis is right about the listen checks. If this is all happening on a dark quiet night, Listen v.Move Silently might be much more important to the Rogue than Spot v. Hide.
