#48 convert to lower bitrate/other formate when syncing

[AndCycle]

for example,

when iTunes syncing with a iPod shuffle,
it can do convert the song to lower bitrates,
because shuffle usually don't have enough room for all the songs.

maybe iTunes Agent can do similar thing?
like convert high bitrates 192kbps LC-AAC to low bitrates HE-AAC for portable device with low storage space?
