	I hope that you are ready to go back to the days of
	using the K(runch disk files option.  Unfortunately, the
	HS/ISO 9660 file systems store files in ranges of 
	contiguous blocks, which is good for speed, but not for
	space.  As far as the filename length, you are limited to 32
	characters under HS/ISO.  About the upper-case-and-numbers-only
	format of ProDOS: ProDOS *does* support upper/lower case now,
	and HS/ISO only support upper case.  Also, HS/ISO both limit
	subdirectories to eight levels of nesting, ProDOS doesn't.
	There are also *numerous* structures in the HS/ISO volumes
	which would need to be updated constantly.
