We are currently working with Linspire to make CNR available under Linux Mint. The CNR server should host Linux Mint software and packages and the CNR client will be made compatible with our distribution.
Once this is in place focus will be put into implementing CNR capabilities into the mintInstall client.
This way you will be able to use the same mintInstall client to install software from both the Linux Mint Software Portal (mint protocol) and the CNR server (CNR protocol).
