There should not be a problem with this as I will explain with an example:
(NB: This is ONLY an example)

The "loot" apon completion of the near impossible quest will consist of many, many riches and the ultimate item.

Once an alliance is formed between a small group of players they can register their alliance with... lets say the king and have a max of say four members. When registering you specify a "leader" and up to three other "looters".

The king then allows them entry to the cave when all other alliances who have come before you have failed to complete the task.

You then have a set time limit to try and get through the cave, solving as many puzzles along the way as you can. The "looters" of the alliance may pick up items and valuables along the way if they can be found. The "leader" cannot.

If you suceed you gain access to the "lost treasury" where only the "leader" can collect the "ultimate treasure" while the "looters" may collect all the items from around the room.

If you have two people who both want the "ultimate treasure" then they can form tow seperate alliances with people who couldn't care less about the "ultimate treasure" and just want the gold and riches they have the chance of getting.
