actually yes.
there is something called a Song Requester Plugin which displays the whole current playlist of winamp on a webserver ( created by plugin itself ) and users can enqueue songs of their choice. If nobody's enqueuing songs, then the songs will carry on playing from playlist just like normal.

( if you want a more comprehensive system, I made a set of php scripts for that purpose too, but its too complicated, you will need a php enabled http server and "Do something" & "httpq" plugins for winamp. only advantage is that it looks prettier and has better shuffle than winamp's shuffle. )
