OK, that means support for one "network" per interface (i.e. what
wpa_supplicant.conf calls network).  That's limiting, of course, but
better than nothing.

That's not what I mean.  I mean, we can have files:

/etc/wpa_supplicant/wpa_supplicant.conf
/etc/wpa_supplicant/wpa_supplicant-wlan0.conf
/etc/wpa_supplicant/wpa_supplicant-wlan1.conf

and so on.  If there is a specific file, it's used for the interface.
Otherwise, the default file is used.

I think wpa_cli should make it possible to pass all configuration
parameters directly from the script.

I don't like scripts writing to /etc, but it's better to have something
working than nothing at all.

Well, that explains the lack of loud screams :-)

The NetworkManager homepage use to say that WPA support is planned, but
I cannot find that page anymore.  I believe I tried NetworkManager on
Fedora 8, and it was only asking for the WEP key.

I'll try it again on a clean Fedora 9 install.
