I originally wrote:

Chris and I have been discussing BigTIFF, as the current Wiki specifies, and we've come to a subject that we both would like more comments and opinions on.

The thing that is now up for debate is the third member, the 'Count' member, the member that specifies the number of values. We are unsure as to whether we really want to keep it 4 bytes, or extend this member to 8 bytes, as well.

In order to try and help ensuring a final conclusion, here is a overview of the founded opinions sofar. I've decided to even eliminate discussions about alignment from this overview, since, by now, it is totally clear that the two issues are not related, because we can/could add pad bytes wherever we want or extend other members or whatever. That also eliminates the original argument pro 4 bytes that I gave in the very first mail, and further narrowes down the discussion quite a bit.
