A TA that does the MP stuff itself isn't a great deal of use with 
standard 115200bps UARTs - link bandwidth is higher than DTR 
bandwidth.

The only way to go is ppp(8), either with two serial connections to 
two TA ports (I guess mpd would work in this scenario) or via an ISDN 
card (the best way) IMHO :-)
