It's a design decision whether your application can play two streams at
a time or only one at a time. If you can only play one at a time and it
is possible to run multiple instances simultaneously, you should use a
normal KApplication. In other cases you should probably use
KUniqueApplication since a single process can handle the desired
behaviour in that case. User preferences should be implemented by the
application itself. The choice between kapplication and
kuniqueapplication is about the design/implementation of your program.
That's none of the users business.
