Glen, I think your idea has merit, and something like this would probably be
the right way to go for any TIFF library. 

However, we first need a specification that describes the details of the new
format.   This new format would _have_ to have the "magic" number changed
since the initial IFD offset will be 8 bytes instead of 4.  If we don't
change the magic we will break all existing TIFF readers.

Could we call this TIFF ? I believe that Adobe has the name trademarked or
copyrighted (whichever is appropriate).  Could we use all the ideas in TIFF
(tags, tag names, etc..) without Adobe's blessing ?  At the start of the
TIFF 6.0 document there is some info on how to request changes to TIFF, but
I have had no success trying to get Adobe to pay attention to me.

Perhaps if everyone on the TIFF list sent email to Adobe, we would get some
action...

Even with the exponential growth we have seen in the last 10 years, I think
that a number that is on the order of the number of atoms in Earth should be
enough to get thru my lifetime :)
