[ALUG] Running vnc server on startup

I want to run a vnc server on startup as a user rather than root and seek opinion to where the best place to put the command tightvncserver :1 -geometry 1280x1024 -depth 16 -pixelformat rgb565 etc/rc.local cron job? Not sure here really if it needs to be before login so thought it prudent to run as a user. Cheers, BJ
