For larger trees, i agree with you. But with a long list of
single files the combined size will be heavily overestimated.
(A reason for having such a list may be incremental backup.
Be praised for option -path-list on this occasion.)
My current method is to use mkisofs -print-size for directories
and stat.st_size+1400 for single files. Not to forget the reserve
space.
Any pointer to better methods would be welcome.

A thorough understanding of mkisofs' understanding of said
standards, to be exacting.

May i predict that you will end up with an own implementation of
an ISO filesystem generator if you follow that road ?
Whatever, i will watch your adventures, if you permit.
Have a nice day :)
