Yes.

If you don't care about seeing the raw 802.11 packets (i.e., if it's OK
to see only LLC packets, and to see them as Ethernet packets), that
should work on any platform.

Otherwise, see

See the FAQ cited above.

No, you just need the right type of network cards and reasonably recent
versions of drivers for those cards.

prismdump, as far as I know, writes out libpcap-format captures, so they
should be readable by Ethereal - or by recent versions of tcpdump, for
that matter - with nothing special needed.
