- only allow connections from PCs with specific MAC addresses (listed)

- WPA (or at the very least 128-bit WEP) security

That's more like it.

Yes, remove temptation by hiding the SSID and setting MAC filtering; for the
determined hackers who penetrate this, rely on WPA. It's a shame that
(AFAIK) a wireless adaptor can't run WEP and WPA at the same time: WPA for
clients that support it and WEP (better than no encryption at all) for those
clients that don't support WEP. Is it still the case that WPA is only
supported on XP and not on Win9x or W2K, or is that restriction no longer
true?

It's covered in something I was reading earlier
