Strong name private key policy - can we get 1.2.10 built with 1.2.9 key?

[Cliff Burger]

To solve my practical problem -- which I'm sure many other people have:

Can someone make available a version of 1.2.10 built with 1.2.9 private key? This would avoid the necessity of rebuilding a reasonably large number of libraries. Alternately: create a FAQ to explain another way around the problem of getting an assembly built to reference 1.2.9 to recognize 1.2.10 without rebuilding. Currently assuming not possible.

Thanks
