Just came across this - Paragon Net Burner 2.0 (Free on registration)
"Paragon Net Burner is a unique utility to “share” a CD/DVD/BD burner over the network and remotely make a CD/DVD/BD recordable device available for use by other networked computers. It gives users the ability to record CDs/DVDs/BDs without having a local burner device. This solution is extremely helpful for notebook users without CD/DVD/BD burning devices onboard. Sharing a HD-DVD/BD device across the network also reduces equipment costs." Paragon Net Burner - Product Tour

Thought many will be interested in this. ( I have not tried because I have an external CD/DVD/BD burner which can be moved around.)
