Of course you are assuming they share a common ground :)  That'll be true a 
lot though.

I like the change.  Any objections or other considerations?  It would be 
nice to have this firm.  I belive what we have now is .. (oops just read 
the updated note on the Wiki suggesting a move of 0V away from the 
3.3V).  Ahem What we have now is ...

pin 1 -  3.3V      n/c  - pin 2
pin 3 - /RST      RxD - pin 4
pin 5 -  P0.14    TxD - pin 6
pin 7 - 0V          -     - pin 8
