Half Life is based on Quake 2 in the same way that a Ferrari is based on a go-kart.
If you''''re going to use a car analogy, you might as well keep it engine-based. Half life (and many other games) use the quake 2 engine, and the engine has been open sourced. However, just like with cars, an engine by itself doesn''''t go anywhere. You need all the other parts that make up a car to drive to the store, and you need all the other (closed source) parts that make up Half Life to play the game.
So no, there will be no Half-Life on the Pandora unless Valve ports it themselves.
Actually, I think Half-Life is based on the Quake 1 engine, which gives you a good idea of just how much was added to it.
As the FAQ says, no source code, no port. Unless someone''s going to embark on the mother of all Quake mods.
