Anyone got any bright ideas for putting multiple serial ports into the empeg? I have a feeling that I'm going to run out as soon as my bgmicro.com order arrives. Ideally (for me), It'd be nice to be able to add 2 more serial ports. That would give me 2 ports for projects, and still allow one for shell access. But I'd settle for one more.

The only real idea that I have at the moment is to use one of the ethernet-based serial multiplexers that are sold for remote console access - but I'm not aware of any cheap options here.
