I had though about this a while back, in terms of a product similar to a
handheld mp3 player -- MP3man, one might say.

You need a ucontroller or uprocessor -- depends, read the rest. You also
need enough EEPROM for n MP3 files. Then enough ROM to hold the decoders,
as well as control software. No, not DOS or windows. Maybe some embedded
version of Linux.

Estimated ROM required: under 512KB.

Estimated EEPROM: for 10 MP3s, or 15-20 Oggs, 50 megs. Round to 64 megs.
Let's say 2 hours of music => 120 minutes, at 1 meg/min giving you 128megs
of EEPROM or a similar-sized magnetic medium (dump the EEPROM).

A serial or paraller (preferred) computer interface, copy songs to it, go
for a walk. Should be easy enough for someone's BE project.
