Jimmy I do believe that Songverter is a 1 computer license. I couldn't find it either on the website about how many for it. But since it doesn't say then I would say that means only one.
Movable? Yes, but if you have an older versions then you will definately have to uninstall it from the current location (while connected to the internet) and then send a Support email to get your registration reset for that computer, then install it in the new location when you get confirmation. If you have the current version you should be able to do it without having to submit the support email.
Do you need it? That depends on what you need to do. You do not want to use it to convert any files to KMA, but let Hoster do that by Importing. Songverter is goos if you need to convert a file or files to another format such as having a music program other than Hoster that will not play the file because it is the wrong format.
