Mostly a note for myself. I'm finally in the process of ripping all the CDs in the house, since hauling them physically to Japan is unappealing. I've had the chumby for ages and I'm a bit disappointed in it's inability to easily play songs from the network and as a result it's been gathering dust.
Tonight I figured out tonight that mount -t nfs pop.lan:/share /mnt/usb will convince chumpy's mp3.x utility that my server is actually a USB drive and now the songs show up under the builtin "my music" player. That just gives me random shuffle which is still pretty crappy but maybe getting somewhere.
