You can use a Maxim MAX3100 SPI to UART.  It costs about $3.  I have an
application where I needed a third UART and it works fine for me.
Philips is coming out with their own version of the MAX3100 at the end
of Q2 or Q3.  It's about half the price, but not pin compatible.

I think you can use independent duty cycles but the frequency would
all be the same.
You could always bit-bang a normal I/O pin for a uart
if it's not too high of baud rate.
