Allowing for 320 bitrate for Slacker?

As Slacker has now increased its maximum streaming bitrate from 128 MP3 to 320 MP3, would it be possible to allow the streaming of Slacker through LMS and mysqueezebox.com to have the option to also stream at the higher bitrate? I only ask because while I can now stream at the higher rate through the iOS app and online, through mysqueezebox.com and LMS I still seem limited to 128 MP3.

Thanks for any help with this.
