I understand why you suggest this, even though archivemount is LGPL, but I digress. FUSE is cool and all but given it's "userspace" and we're just reading a single file here, I don't find this compelling versus reading from a block device in-process. TFA is compelling because it's compression over specific data sets without being in the hot path for every operation. Putting a sqlite.db in a tarball is... problematic. There is no random access, so if your database doesn't fit in memory/cache, performance will be abysmal.
