[Haskell-cafe] wlan library

Hi *^o^*, I am writing a network manager http://sert.homedns.org/hnm/ as a replacement for some broken, already existing knetworkmanager for a friend's computer. I was looking for some haskell libraries that provide access to wlan cards but could not find any on hackage. Maybe I missed something. Currently my tool is using linux the commands: modprobe, ifconfig, iwconfig, iwlist, dhclient etc.. Can a library calling external stand-alone linux commands be considered good enough as is? Or should one definitely write a wrapper around a more low-level, stable, POSIX-compliant foreign library to access and configure, control WLAN cards? I'd love to hear your comments.
