Mucho $$ yes, but an option.  The carrier that I have can swing both
ways:  eSATA or USB.  Bottlenecks aside it gives flexibility when you
can get it (and I like flexibility).  Build a multi-boot system there
and viola.  My first choice is USB stick though.  Low tech, easy to
carry and replace.  Just watch them going through airport security
scanners.  I've had a few fried by their equipment in repeated scans.
I'm starting to carry LPS (DoD-SPI) with me as a back-up.........R
