Multicast :is not useful because it is not deployed. But people don't deploy it because :they don't see it as useful, because people don't use it much because :they feel they can't reach everyone. : : This needs to change, but this is not the correct fourm for that :change. :... : : - jared No, it is not deployed because of a lack of interest. Lots of people are interested. We went through all that at BEST ... Except for Alternet none of the backbones were willing to even contemplate multicast routing (pim or anything else) because they simply had no way to manage their network bandwidth (to handle it) *OR* to bill for it. The situation hasn't changed. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
