Upstream bandwidth, quality and delay limits of video transmission via the Internet. How is video transmission useful for people with disabilities? People who cannot hear will not be able to hear the people they are talking with and people who cannot see will not be able to see the video.

Can you enlighten us why VoIP software should deal with this issue at all? VoIP software needs to provide an interface for passing suitable notifications to other software. It is necessary to have a way to register a callback and a way to call the registered callback when those events occur. Or a FIFO (a pipe) or a TCP socket (or UDP if we can afford to miss event notifications because the notifications will repeat until the sleepy user with hair frozen by icy water - see below - acknowledges them). [Remember that as far as VoIP is concerned, I fell yesterday from Mars and know practically nothing about it (no reason to learn about it...). So I state points, which may be annoyingly obvious and trivial to VoIP old-timers.] The other software can then perform any specialized hardware manipulations it needs (such as operating a robotic arm which will pour ice cold water on the head of the sleeping user). In my opinion, not every application should deal on its own with alerting the user, because a standard solution already exists: The X Windows beep. Does VoIP software interface with the X-Window beep in a standard way? Not only does it not require modifying every little application, and it is completely standard in the X-using world (not specific to Linux, KDE, Fedora, or anything of that sort), it even works when you run remote applications, like good old X was supposed to support.

Yes, please show me.
Here's a first - source code on this open-source list :-) But it's so short,
I hope nobody minds. I took out the ESD sound playing code (which is obviously
of no interest to you), and left only the minimal capturing code. You can
replace the silly printf with anything you want.
You might also want to check out xsoundentry (if available on your system)
and fancybell (http://www.hypercore.co.jp/opensource/fancybell/) on which
my code was orignally based.
Compile the following code with cc file.c -L/usr/X11R6/lib -lX11 (or
something similar).
/* capture bell events (using Xkb extensions) and do something.
*/
#include stdio.h
#include X11/XKBlib.h
int main(int argc, char **argv){
Display *dpy;
unsigned int bit1 = XkbAudibleBellMask, bit2 = XkbAudibleBellMask;
XEvent event;
int major = XkbMajorVersion, minor = XkbMinorVersion, Xkb_event_base;
if(!(dpy=XOpenDisplay(NULL))){
fprintf(stderr,%s: Unable to open display\n,argv[0]);
exit(1);
}
/* initialize Xkb */
if (!XkbLibraryVersion(major, minor) ||
!XkbQueryExtension(dpy, NULL, Xkb_event_base, NULL, major,
minor)){
fprintf(stderr,%s: No Xkb extension on display?\n,argv[0]);
XCloseDisplay(dpy);
exit(1);
}
XkbSelectEvents(dpy, XkbUseCoreKbd, XkbBellNotifyMask,
XkbBellNotifyMask);
XkbSetAutoResetControls(dpy, XkbAudibleBellMask, bit1, bit2);
XkbChangeEnabledControls(dpy, XkbUseCoreKbd, XkbAudibleBellMask, 0);
/* event loop, wait for beeps */
for(;;){
XNextEvent(dpy,event);
if(event.type == Xkb_event_base
((XkbEvent *)event)-any.xkb_type == XkbBellNotify){
fprintf(stderr,bell!\n);
}
}
XCloseDisplay(dpy);
return 0;
}

Or maybe just people who want to communicate using their everyday medium of communication, sign language, over a network. Why should this be treated any differently than voice?

How many of those are there anyway? At least in Israel, more than you think. They have children or parents or spouses or siblings with normal reading ability, hence the use of more sophisticated computing equipment. Since the 2002 series of demonstrations by the Deaf, people who are deaf from birth or from before age 3 are entitled to buy accessibility equipment with up to 4000 NIS paid for by the government, once per 4 years. The list of equipment is fairly long and includes computers and webcams as well as FAX machines. Currently, MS-Windows XP reigns supreme in this arena. --- Omer P.S.: [OFFTOPIC - if you reply to this, please reply on the Linux-IL mailing list] Did anyone succeed in making use of the Trust TwinkleCam (according to Device Manager, it identifies itself as Chicony TwinkleCam, vendor Divio, vendor ID 0x06a5, product ID 0xd800) under Debian Sarge with kernel 2.6.8-1-686?
