Proposal:

* Usage: user prepends "--bzip2-filter=lbzip2" to her TAR_OPTIONS.

* On Debian, the tar source could be patched, so that "bzip2_filter"
 defaults to "/etc/alternatives/bzip2-filter", which would be a symlink to
 /bin/bzip2 per default. Packages like "lbzip2" and "pbzip2" would add
 alternatives.

* User sets specific options for her choice of bzip2-filter by setting appropriate environment variables. For example,

export LBZIP2_WORKER_THREADS=2
export LBZIP2_PRINT_STATS=1

Thanks,
