To be more exact, in general the tar command should be:

tar cfz - ./local | ssh machine 'cd <target dir>; tar xpfz -'

note the ``p'' in the second tar preserves the owner and group 
information along with the file modes, which might be critical 
depending on who owns the files.  Not including it has bitten be in the 
past.  One additional problem is that both machines need to have the 
same user owner and group id's.
