I went to a community/adult learning college in London who were offering courses in music tech and production and asked them what software they used and Sonar was not one of them Reason, Logic, Protools and Cubase is pretty much what you'll find in the UK although that was about 6 years ago so I rekon Albleton and maybe even Reaper will be on offer now.
When I asked about Sonar they said, no but if you're interested in running courses your self then please do feel free :)
Of course another on line education in sonar and all things to do with music production is right here on this very forum, trouble is you'll find equal amounts of conjecture along side, "and often disguised", as fact :(
