Hi Owen,
Thanks for your erudite reply.

I am actually well aware of all of the technical meanings of the word
bandwidth. However, I was using the word in the colloquial sense -- that
is bandwidth as a limited commodity which costs money.

After a certain limit my host charges by the megabyte. So I do not want
to pay for anyone to view this video clip, just the people that I send
the link to. So yes I am talking about controlling access. However I do
not care if a recipient emails the video clip as an attachment to a
friend. I just do not want that friend accessing my web server. Making a
scalar count of the number of times the file has been downloaded would
also serve my purpose as it would allow me to cap the bandwidth cost of
this mail out. I am not concerned about the number of concurrent
connections so I do not need throttling. I am concerned about minimising
the number of megabytes of data delivered by my web server.

Yes. But I don't care if they receive the file as an attachment.

Regards,

David
