General Petraeus' idea is to start dealing with "less extreme" elements of the Taliban. Something like this was done in Iraq, when America talked with Sunni tribes who eventually helped kick Al Qaeda out of Iraq.1
If the plan goes through, the Afghan government will be handling the talks: with "active participation" by America.
I think it makes sense. Individuals, and groups, may have many reasons for teaming up with the Taliban - if they're not like the Iraqi kooks who killed a man for wearing trousers, and not praying.

Don't tell the Code Pink crowd, though. They might get (more) upset.
