Maybe that's true for the current implementation of tar for Windows NT,
but it certainly can be done. In the OS/2 version of tar there's room
for EA's and IBM LanServer ACL's, both of which are variable length. 
The tar format is compatible with Unix tar, although the Unix versions
of course cannot extract LanServer ACL's and EA's: they're ignored.

Maybe it's a good idea to look at the sources of tar for OS/2 and
port it to NT. For NT's HPFS it might be really easy.
