purple-remote vs sudo

[Louise Baldwin]

How can I get purple-remote to work through sudo? The scenario is that I have a root cron job which automates several sequential tasks, some of which must be run as the "Louise" user. The other scripts/commands work fine using sudo, but purple-remote getstatus returns "No existing libpurple instance detected" despite that there is in fact an instance of Pidgin running for user "Louise" -- what is causing this discrepancy?
