It is both possible and desirable. The 'posix' format is an extension on 
top of the 'ustar' format, so I plan to make tarlz use a "limited posix 
format"; 'ustar' where posible and 'posix' only on the files requiring 
it for any reason (long name, large size). This removes all limitations 
while remaining as compatible and simple as possible.

Sure. Suggestions are welcome. :-)

Here you can find the specification of the 'ustar' and 'posix' (pax) 
formats:

Glad to know that tarlz is already useful to someone. :-)
