report to the uvc driver developers devlist or just dont use flourescent 
lamps, a problem for every image sensor, even professional TV studio 
cameras, the cameras firmware should do that, besides.
if youre in an office environment, complain to the electrician company who 
has build the office's flourescent lights without 3 phase shifting. a violation 
of electrical building assembling standards and therefore a warranty case.

there can be no flicker over home users net, 
because of low transfer framerate, pls try adjusting your vga cards 
vertical refresh frequency in XF86Config or trash a defective display or vga card.

h.264, there a free projects around but maybe not mature enough, yet, 
and U.S. patent issues.

no. user space program's work. and RTFM, zooming is already in ekiga.
and stop comparing paid winXP and proprietary toys with linux sw, pls, we've other 
priorities than just copying window$ and proprietary software features.

> > Fourth wish: add File Transfer function to Ekiga

denied. IRC DCC, FTP, or SSH is sufficent for file transfer on UNIX/LINUX and 
more secure and stable, and open standards, get used to it. 
we dont need 10 messengers like msn or aim on linux around, 
the only reason for their existence is that window$ 
lacks standard internet capabillities and protocols and prefers proprietary protocols. 
we dont really need and support that messenger proprietary protocol chaos on linux, never. 

...

forseeable no budget for such luxury wishes, i think.
if you want all that in pls donate at least 150 US$ to ekiga.org 
project as you payed license fees for winXP and the windows driver 
of the webcam, thx. ;)
