@Drone7, I believe the answer is no, Sonar doesn't attempt to push updates for products they bundle with Sonar like Nomad plugs, Blue Cat, Melodyne etc.
For most, there is a way to check for updates, but Nomad doesn't make it too obvious as to whether you need to update. They just give the date of the most recent installer.
BlueTubes=Nomad and you can download the installer from here...
http://www.nomadfactory.com/downloads/index.html I have a license for their integral plugin pack and I just downloaded the latest installer for Windows and re-installed. Then Rescanned VSTs in Sonar. I did not have to re-authorize the plugins after doing this (by that I mean drag the license file to the plugin). You may find you have to go through the installer and tick each plugin you want to update, which looks to be a pain.
This was the link I used for the 64 bit install for Nomad listed under 'Other Nomad Factory Software'...
