As far as I've ever found, without multicast it wont work.  Those apps just 
aren't made for the enterprise.  Our campus WLANs don't have multicast and so 
most of the iPhone "find it" style apps don't work here. We did notice that the 
test SSID that has IPv6 enabled does allow the multicast based apps to work, 
even though IPv4 multicast isn't on.  Depending on your situation, that might 
be something you can work with, since the iDevices all speak v6, and v6 has to 
use some multicast.
