A great concept, but a few kinks to work out. I created an alias tonight (at 7:43pm MDT on Aug 9) and the date shows Aug 10, so perhaps relay.firefox.com is only showing UTC? Would be great if it were localized. Additionally, 5 free aliases is great for free, but a service like this really depends heavily on the ability to create unlimited aliases... I hope that that feature will be reasonably priced.
