--- Comment #2 from Dennis Lubert <plasmahh at gmx dot net> ---
One (probably easy to solve) problem with something like fuse archivemount is,
that it only mounts archives, so you have to create a tar.gz from it. Those
file formats complicate things somewhat, and generally people do just want to
compress the files (I do it with xz btw., which makes them factors smaller than
gz)

Another point is (and I stumbled over this report because I wanted such a
feature too) that you often have to debug on systems where this is not
possible. In a company you don't have the necessary priviliges to install the
fuse stuff, your kernel and/or userspace tools are too old. And you have to
debug on the system where the core file is, because you have no other system
with the same .so files and other stuff installed. It might be on a customers
machine where all you have is your statically linked gdb...

It might not be desireable to pull dependencies of compression libraries in,
but maybe gdb can support them via dlopen, and then support gz/bz2/xz/whatever
if it is present.
