I think of something:
- using netlink or similar interface

If you're doing a new config interface, I'd suggest netlink like the
wireless guys did to replace WEXT with cfg80211.  Using netlink makes
your interface easily available from programs/libraries without having
to screenscrape anything.  If you want some advice on netlink API stuff,
ask Johannes Berg.

Thanks for your mail. It seems I'll do it this way.
