When an accomplishments collection is added or removed, we need to send 
the reload signal to all instances of the daemon.  I have code in the 
postrm/postinst steps that does this finally (below), but sudo -u 
{$user} just isn't enough due to the way the daemon looks for the PID 
file, I think.  I considered modifying the daemon to accept a --user 
argument, but due to the way we look up the cache directory, I'm not 
sure that helps either.  The brief question is: using sudo, how can I 
call /usr/bin/accomplishments-daemon --reload for another user.  If you 
can solve that I have the rest of this issue solved.

Here's the postinst/postrm code that will go into the collections and 
the output follows:

#!/bin/sh -e

if [ -x /usr/bin/accomplishments-daemon ];
then
    for user in `ps -ef | grep /usr/bin/accomplishments-daemon | grep 
/usr/bin/python | grep -v grep | awk '{ print $1 }'`; do
        echo "Reloading accomplishments for ${user}"
        sudo -u ${user} /usr/bin/accomplishments-daemon --reload
    done
fi
