Theres not much. There are almost no good DAAP/RSP clients for windows. iTunes of course but its bloatware.
There is a very crappy/alpha plugin for winamp. winamp out of the box wont do and any other streaming clients also not.
There is GIT aka Get It Together as java client.
There is the flash and java client built into firefly which is also beeign developed – look at the third party page.
There is a tool to create a playlist with streams out of a RSP database but thats a workaround and the mt-daapd crashes with some clients when you use it. Not to speak its really a warkaround and you need to regenerate the playlist on every db change — not good.
There are good clients for linux though. Amarok etc.
