A quick comment on the "all mac" question. We have worked very very hard to
get Apple to help us get QuickTime Support for the streaming media tools.
Apple has been unable to give us the information we require to make QT based
tools work.

If you are interested in how to help please email the list and either Tom or
I will try to tell you what can be done.
