Yup, I agree with that in principle. What about if they only have a 100mb/s switch or hub though?

Don't get me wrong, I think unicast is the way forward at the moment. 

However, I think that whatever is put in place, should be done with the idea that sometime in the future, multicast could be implemented /safely/ and an 'upgrade' to multicast should be coded in easily.
