Live Feed questions

[kbone1]

I'm looking for information on how to set up a solid live feed viewable from a website. I've tried googling different phrases, ie "how to set up a live feed" etc etc, but for the most part all I get are tutorials on how to set security-related feeds.

Basically I would like to set something up like a "beach cam" that some local beach cities' websites have, where it shows the live feed of the beach conditions etc. Preferably i'd like to set up this live feed so others can access it easily via bla bla bla dot com .

Any good sites I can check out?

Anyone have any idea what kind of equipment I need to set up one feed? Is it possible to have 3+ feeds on the web site (asking from a resource point of view)? Are these feeds expensive to maintain?

Thanks. Any information, any at all, will be much appreciated.
