Some more answers to myself :-)

I have found a way to import a key to another machine using the
RSACryptoServiceProvide.
However it does not work with keys created by the sn.exe tool, there is an
exception when trying to decrypt/export such keys - any idea why?

steps:
- Create a new key in a named container (cspparameters)
- Export to xml (public + private)
- Go to the other machine
-Create RSACryptoServiceProvide with the same params for the CSP as above
-Call rsa...fromXml (use the output xml created above)
- rsa... PersistKey ..
- And it works - now the 2 machines use the same private key

Thanks
