It's bitrate, which is the typical measure, so bits not bytes. It also 
takes whole numbers. I suppose it could be made to take decimal points 
but that was not my focus initially. It should be case insensitive though.

300K would be 300 kilobits/s, I don't know what you are feeding but that 
would be a high limit for audio (assuming the limit-rate setting).

a limit-rate won't prevent a source client connecting, as there is no 
stream at that stage, but a stream could drop before a listener connects.
