       objects of the document. Shared objects, such as fonts, are included
       in the file after the page contents. When downloading the optimized
       file from a host, the page offset information is read early and is
       used to download a specific page requested by the user without
       downloading other pages in the document.

If the only "new" thing here is a table of contents at the beginning,
I would expect there is enough prior art for this.  Meanwhile, at

would be good to find a way to wrest effective control of the format
away form Adobe.
