streaming video on the net

[TP]

I am interested in streaming video on the internet for personal use (so my family across the country can see the kids...). I family have the capturing capabilities and want the easiest and cheapest way to turn this into streaming media. Anybody out there got advice as far as software? Also, in case you know this too, what are the hosting requirements? Do free webhosting services like Tripod support streaming video? Thanks.
