I ended up doing something similar but was concerned about name collisions
within the top level.  That is, what happens if two people both want to have a
file or folder called "foo"?

Instead I create a unique share within the public folder (called "scratch")
for each user on the fly.  Here's how I set this up.  First the share
definition:

[scratch]
  guest ok = no
  path = /scratch/%u
  read only = no
  root preexec = /var/local/etc/scratch.preexec %u %g

The scratch.preexec script makes sure that /scratch/%u exists and sets the
correct ownership permissions.  Here's what the script looks like:

#!/bin/sh

exec >> /dev/null 2>&1

ntuser=$1
group=$2

umask 22

if [ ! -d /scratch/${ntuser} ]
then
  mkdir /scratch/${ntuser}
  chown ${ntuser}:${group} /scratch/${ntuser}
fi

exit 0


The only drawback in this scheme is that users can not easily access each
other's scratch files.  I hope this helps.
