Haven't been able to find this...
I'm finishing up a site that has several webcams (doggy daycare business). My client is now concerned about how many folks could sit with the webcams running during the day watching their dogs play while the humans work. What is the risk of crashing the site. Is there a bandwidth limit? Other concerns in this situation?

Thanks for any info or help!

This is controlled by your host. Check with them to see how much the current plan allows. You'll also need to calculate about how much you will be using and they can probably help you with that.
Here's an article that explains the ins and outs of it.
