Microcontroller with many UARTS

Your other option is to connect to something like an Octal UART which 
provides 8 serial ports.  There is no reason that you couldn't connect 
to multiple of them as long as you had the processing power to service 
that many devices.

Examples are:

SCC2698B from Phillips
XR16L788 from Exar
