There is no chance IMHO that borders in the region will change, but I am aware that some see a "fix" in:

1) Granting the FATA full provincial status and integration into Pakistan
2) NWFP losing any "oversight" of the FATA
3) Afghanistan recongnising the Durand Line as the border

Apparently an idea that is floating around inside and beyond Pakistan. Not sure of the dynamics and practicalities from this armchair.
