Over 500 clients of Xtra voluntarily registered and received Radio New Zealand and BBC World Live as Multicast on Telecoms dial up service for 3 years from 1998.

I attended and observed when Telecom engineers enabled the same service via adsl in Wellington as multicast sourced from my servers in Akl in 2000.

What I'm looking for is someone who has _today_ content which they want to distribute where a) the availability of IP multicasting could reasonably be expected to make some difference to customer experience/network load, and b) the level of demand for this content can reasonably be expected to be such that either extra revenue for someone would come from making that content available OR its availability can reasonably be expected to increase the uptake of broadband service. The first of these is actually a harder test than it looks, given that there are other ways of doing point to multipoint comunication than unvarnished IP unicast or multicast. (The classic way to allow download of big documents many times is with proxy caching, to take just one example.) - Donald Neal All opinions my own. ------------------------------------------------------------------------------ "This communication, including any attachments, is confidential.
