Just make sure you're running the very latest kernel with
CONFIG_SYSFS_DEPRECATED disabled (I think that's necessary, not entirely
sure). You'll notice when anything but the current CVS version of HAL no
longer displays network devices :/

Yup, it is. But there's still debate on whether it should be done
through netlink (nl80211) or some new special injection format for the
monitor interfaces like the management interface currently has.

[you can rip code from wpa_supplicant to inject frames]

Btw, here's another argument against the monitor interfaces: having them
up takes the card out of powersave mode which they should only be while
not associated, even with a userspace MLME.
