There shouldn't be any compatibility issues. Any that arise are p1 bugs 
for NSS upstream. We specifically design new versions to slide in under 
old versions so older apps can always user a newer version of NSS.

We (the NSS team) ran into a similiar issue with Umbuntu. After 
discussing with their packager, we've resolved that future versions 
would have the libnss3.so name without the extension.
