Great news ! Damien Sandras will be happy. I've had a look at pwlib. The code 
is quite clean, but I don't have time to do it myself, so I'm glad you 
offered your help.

I don't think it will be a problem to link to libjpeg (even if Damien would 
rather avoid it if possible). Remember that the MJPEG data doesn't contain 
the Huffman tables, so you need to add them manually (see the Qt patch I 
posted on this list).

Why did you need to modify the driver ?

I'll see if I can code MJPEG support for Kopete in the not-so-distant future. 
I'm currently working on adding proper controls support to the driver.
