Is this really the end of Dreamboxes when N3 hits? or will someone find another way (hack it), or is there an way around it just now?

I have DM500c Black version. Parents and bro in law has the white original one all on VM and we in Lanarkshire. I am dreading it I have a new TV coming in in the following two weeks. I don't want to lose all the Sky movies and sports and all the other channels.
