Enumerate?  It can just ask LAR what files are there.  Put all
payloads in some subdir or whatever, low-tech is good ;-P

You can keep the headers uncompressed by, well, keeping the headers
uncompressed!  This has nothing to do with the binary format used,
but everything to do with how you use your compressors.

Why do you need the headers uncompressed, anyway?  Any sane
compression library allows you to ask "give me the first nnn bytes".

Why do you want to load individual segments?  When would this be

Again, that is more a feature of your compression than a feature
of the binary format.

Why is an extra copying step harmful, btw?  Not because of the
few milliseconds that copying costs, even on the lowest-end
