`(new) The apparatus of claim 33, wherein the transceiver transmits a profile of the first
`
`apparatus and receives a profile of one or more other apparatuses.
`
`36.
`
`(new) The apparatus of claim 35, wherein the profile comprises at least one characteristic
`
`selected from a set consisting of a characteristic of the user of the apparatus and a characteristic
`

`
`maintenance of the ad-hoc network if the match exceeds a predetermined value.
`
`41.
`
`(new) The apparatus of claim 33, wherein the music to be played on the first apparatus
`
`and the other apparatus is stored only on the first apparatus, and wherein the stored music is
`transmitted to the other apparatus for playing of the music on the other apparatus.
`
`(new) The apparatus of claim 33, wherein the music to be played on the first apparatus
`42.
`and the other apparatus is stored locally on both apparatuses, and the music is played on the other
`apparatus from the local store subsequent to an instruction from the first apparatus.
`
`43.

`identify the first listening apparatus.
`
`45.
`
`(new) The apparatus of claim 33 further comprising a plurality of channels for
`
`communicating between the first apparatus and one or more other apparatuses, wherein the
`plurality of channels include at least orie public channel and at least one private channel.

`
`(new) A method for sharing music between a first music playback device, and a second
`
`music playback device of the same type, comprising the steps of:
`
`exchanging wireless messages between the first and the second music playback devices,
`
`wherein exchanging messages establishes an ad-hoc network between the first and the
