ACA has posted an interesting “Israeli proposal”:http://armscontrol.org/pdf/20070927_Israeli_NSG_Proposal.pdf submitted to the NSG last March. It details a criteria-based approach for future NSG-states cooperation with countries that never bothered to sign the NPT.
Both the proposal and the “accompanying media advisory”:http://armscontrol.org/pressroom/2007/20070927_IsraelNSG.asp make for interesting reading. For geeks, anyway.
