  Interesting.  I've seen removable media used as backups (I worked for a
time at a Winn Dixie distribution center and part of my job was driving a
few tape cartridges of critical data off site to a secure facility and
bringing back previous tapes) and I right now carry a USB key with signed
certificates so I can log into work from any Internet capable PC with a web
browser (and copies of puTTY, a Windows SSH client since it's a 90% chance
that any Internet capable PC will be running Windows).  

  And never underestimate the bandwidth [1] of a station wagon loaded with
tapes [2].

  -spc (Hmm ... I just noticed my removable 1T external harddrive ... )

[1]	Or technically, would it be throughput?

[2]	I remember hearing that at some point in the 80s/very early 90s, it
	was faster to airship tapes of USENET than to transmit USENET via
	copper (daily flights).
