John,

Some people have successfully extended leads from the sxKey to the chip being programmed and debugged.  However, it is [b]not[/b] recommended as the clock that drives the SX chip is on those leads.  If you're working on a project with a 50 or 75 MHz clock, that means you'll be sending that high speed signal across your extensions.  If it works - great.  If not, don't be surprised.  

Extending the serial cable and using a ribbon cable for strain relief is a safe approach.
