"Now playing" announce?

[Halo]

Anyone talented with coding like to have a shot at a announce that shows a standard announce, then fade out to another announce, one after the other with no time limit. (eg keeps going until "stop display" is pressed) Perhaps controlled via the web interface with four text boxes, each displayed for 5 seconds.

I'm thinking this would be awesome for those running standalone R4, but want to have a "now playing", "next song" & maybe a drink special too.
