portability of tar tapes

How portable are tar tapes from one machine to another. My experience
has been that tar within a vendor's site is portable but to try to
carry a tar 1/4" tape from one vendor to another --- that's another story.

The only thing I've had luck with is 1600 bpi reel tapes written in cpio -
which is definitely not friendly to the casual user.
