all of tar's limitations will have to do with the output file.   
typically, you'll run into problems at 2 gigs on some old kernels, or  
*nix variants.  tar used to have a limit of like 8 gigs or so,  
assuming the underlying kernel/filesystem would allow it....but I  
haven't tried to push that limit in quite a while.  For instance, 4  
gigs is where you crash if writing to a fat32 partition.
