+1 for motion, it works very well (is being developed afaik), gives you
live view as well as frame capture.

the bug bear for scaling up is you do need a usb controller (not just a
usb port) per camera if you want anywhere near sensible resolution with
usb webcams.  however i find i can normally get away with two cameras
hooked up to my routers so that i know who last touched them. 
this is not a motion issue, it is a hardware bandwidth issue.

you might like to roll your own ip cam by taking a raspberry
pi+gentoo+usb webcam(+powered usb hub) - still v.cheap.
alternatively consider a dedicated mpeg2 (hmm showing my age i think)
capture card which has multiple inputs. you can find a list of
compatible devices at the motion website
http://www.lavrsen.dk/foswiki/bin/view/Motion/WorkingDevices

it is the hardware that is the issue -- not the software.
if you are looking to have like a security wall with 30 odd cameras all
showing the a different view of your secure area, all you need is a web
front end that connects an html table with each piece of the table a
live view of each camera.  you could therefore easily have 100+ seperate
computers each with two cameras, and the only piece of kit that would
struggle would be the end computer that would try to stream 200 camera
images scaled down to fit !

one more thing is that there is an android app (i'm sure there are many
but i can say this one works) called ip webcam which lets you bookmark
all your motion live cams, meaning that you could then check security
status from anywhere using your phone.
not sure if you can do that with the other programs, maybe someone else
can chip in if they know.
