sorry if this is the wrong place.

which has been out longer? what are the main differences between each?

I have run knoppix before but I have not run ubuntu. However I thought that I read that the latter was more popular? Does anyone have any outside links to other sources to confirm/dispute this?

I am looking at setting htis up for a few older people and I figure we can put firefox, thunderbird and open office on there.

I am just wondering about a live update feature which ubuntu seems to have, a firewall , virus & spyware detector. (which I didnt see but may have missed) I would like the firewall program to ask permission for all outgoing connections made, a bit like zonealarm.

Finally sometime in the future (after I use it much more) is it possible to remote suport via a gui interface for either one?

Thanks!
