golden chute

http://yellowmug.com/filechute/

if you haven't checked this one out yet, do it. it's the perfect file swapping add-on for your dot mac account. slicker ui than webdav, way faster upload times than finder drag-n-drop, and it's a breeze to use: simply drag your deliverables into the "chute" icon and email the resultant download link to all your pals. and it's windows friendly too!

the latest version has a nifty "progress bar" icon that gives you an instant status update on your uploads right from the dock or finder.

the only downside is the fact that this functionality really should have been built into dot mac in the first place. oh well - onward to leopard.....
