I've already made my ruling on this but I thought I would get some more opinions from the smart people here as to what the RAW should be.
Ranger with Staff Fighting feat from Dragon: Allows PC to treat a staff as a double weapon.
Relevant rules section on double weapons is page 10 of AV a block in the lower right corner. Using a +2 Staff of the Serpent also from AV IIRC. This item has a property --paraphrase-- that adds +1d6 poison damage to every melee attack.
Using Twin-strike what would the damage be --for purposes of this ignore the Hunter's Quarry-- and list what you think each attack would do.
I hope I have left my opinion out of this and just presented the relevant rules texts that I consulted in making this ruling. If I missed anything feel free to add a reference with book/page.
