Do you get audio on your laptop when not doing --sout ?? Test this first.

With two vlc's? Or do you mean streaming the same webcam to the two iPAQ's?

In the second case you need to stream to a multicast address, eg: 
239.0.0.1 from the laptop. The iPAQ's then need to listen to that 
address, with: vlc udp://@239.0.0.1:1234 -vv
There is one caveat here, your tiny network probably needs a multicast 
router in this case. At least you need to add some rules to the routing 
table on the laptop (if not present already) and on the iPAQ'w. Here is 
the route you need to add:

/sbin/route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0

The resolution is primarily controlled by the webcam. If you are 
streaming with a webcam resolution bigger then 320x240, then that is 
wasted effort, because you won't be able to view it on a iPAQ. It has 
only a screen size of 320x240.
