Palm Sounds report on Belkin's great-looking TuneStudio iPod portastudio, which can record 4 tracks mixer - which can mix four tracks into a two channel recording on a 5G ipod. You can nearly do the same thing with a Behringer mixer and a Tune Talk (although there will be a level problem as the Tune Talk only has a mic input). But this thing is cute and knobby, and $180 isn't a terrible price. Alternatively, for $99 you can stay strictly old-school on cassette with the Tascam MFP01 which is actually sold with the line "Records one track at a time with classic warm analog sound"... (More coverage of the TuneStudio at iLounge, Engadget and Gizmodo.) (Thanks to everyone in the comments for explaining this story back to me...)
