Mac Sound Scheme

Hi there guys! I've had a Mac (OS X 10.5) for almost a year now, and I've recently been wondering whether there would be any possible way to create a 'sound scheme' (or at least get the Mac to make a sound every time i log on or off.)
-- I do know about adding a sound file to 'login items' in system preferences, but that's not really what I'm after.

And before any of you suggest 'Xsounds,' - I've tried that, doesnt work on Mac OS 10!!

Cheers for any help I can get!

application I could use in order to create a sound scheme for when i log in or out?

Does anybody know of anything?
Or am I just completely alone on this?
Please help!
