What problem are we talking about exactly, and with what shell?

$ uname -sr
FreeBSD 6.1-RELEASE-p17-jc1
$ /bin/sh
$ FOO='with spaces'
$ echo $FOO
with spaces
$ OK=$FOO; export OK
$ sh -c 'echo $OK'
with spaces
$ export BAD=$FOO
$ sh -c 'echo $BAD'
with
$ echo $BAD
with

I'd write
export BAD="$FOO"
anyhow.  And also OK="$FOO" by the way.  The alternatives scare me.
