Where on earth did you offer? I'm a Demon customer and NetBSD developer and
I'd love to see an Alcatel Speedtouch driver for NetBSD. Last rumour I heard
was that BT put a stop to the OpenSource driver being developed by an
Alcatel engineer. Alcatel are currently saying there are going to offer a
closed source driver - I guess for Linux only.
