Interesting idea for BigTIFF. We had a customer just yesterday complaining that appending a TIFF takes too long on an existing TIFF with 2000 pages.

PDF's weak point is its elaborate complexity. But that is also its main strength, and your need might prove that too. I'm not a PDF expert, but if I remember correctly, PDF can contain a sortoff hash table for page offsets, that allows you to quickly locate last page and all.

You are correct - it's called the xref.

In addition to that, PDF is also very suitable for update as opposed to rewrite.

Very much so. It specifically has an "update mode", where you just append stuff to the end w/o touching any of the original.
