Today while using Reflector I've noticed one funny thing. It came out, that we are able to see where Microsoft keeps their PublicKey files and what are their names 
Few samples:
| mscorlib | f:\RedBits\Tools\devdiv\EcmaPublicKey.snk |
| System.Data.Linq | f:\dd\tools\devdiv\EcmaPublicKey.snk |
| System.Web | f:\RedBits\Tools\devdiv\FinalPublicKey.snk |
| Microsoft.VisualBasic | f:\\RedBits\\Tools\\devdiv\\FinalPublicKey.snk |
Nothing special, but... Keep this in mind when doing RTM so you don't something that shouldn't be distributed, like: CustomersIHate\Customer1\Key.snk
