OK, I inadvertently sent a chain of stream-of-consciousness replies
directly to Kim and not to the list, which is just as well for most of
you. :) Here's the upshot:
1. "do shell script" defaults to a "shell" of /bin/sh, which doesn't
have process substitution, hence the need to invoke bash explicitly.
(tcsh also doesn't have process substitution, which is why it didn't
work in Andrew's Terminal session.)
2. /bin/sh on OS X (at least since Panther) is in fact bash in
"sh-compatible" mode - which, like vanilla sh, doesn't have process
substitution, so (1) still applies. However, *unlike* vanilla sh,
bash in compatibility mode has both the "source" command and
tilde-substitution. Which is why the "source ~/.profile" line worked.
3. A more compact way to achieve the desired result is to tell bash
on the command line that you want it to run the .profile, which you
can do via the --login option:
do shell script "bash --login -c 'ls >(ls)' "
<http://developer.apple.com/technotes/tn2002/tn2065.html> would have
answered the first two points directly and the third indirectly. If
you plan to be using "do shell script" on a regular basis, you should
probably read it.

P.S.: I still don't understand what that command is supposed to do,
but then I've never understood named pipes, either.
