Also, a follow-up to aid my understanding.

There is a limit of 2^32 pages (because of
page_sequence_number), and a page has
a maximum size of 65,307 bytes (of which
256 * 255 bytes can be "useful" data).

Many thanks,
Martin

How is this 65307 number calculated ?
255 segments of 255 bytes yields 65025, and this 65307
number is also mentioned in the ogg docs (framing.html).
The difference between the two numbers is 82, a rather
odd number that doesn't give me a hint as to the answer.
