Look at this;
March 2001 (C): Taliban envoy Rahmatullah Hashimi meets with reporters, middle-ranking State Department bureaucrats and private Afghanistan experts in Washington. He carries a gift carpet and a letter from Afghan leader Mullah Omar for President Bush. He discusses turning bin Laden over, but the US wants to be handed bin Laden and the Taliban want to turn him over to some third country. A CIA official later says: "We never heard what they were trying to say." "We had no common language. Ours was, 'Give up bin Laden.' They were saying, 'Do something to help us give him up.' ... I have no doubts they wanted to get rid of him. He was a pain in the neck." Others claim the Taliban were never sincere. About 20 more meetings on giving up bin Laden take place up till 9/11, all fruitless.
Hashimi also proposes that the Taliban would hold bin Laden in one location long enough for the US to locate and destroy him. However, this offer is refused. This is according to Laila Helms, daughter of former CIA director Richard Helms, who is doing public relations for the Taliban at the time (while interesting this came out before 9/11, one must be skeptical if the offer was made since her job was public relations for the Taliban).
