You can read in the directories for tar from standard input. So you 
could do something like:

ls <WHATEVER PATTERN> > .file
tar -cz `cat .file`

Obviously you could also put the ls into the backquotes. I tend to put 
them in a file so I can email myself a list with no risk of that 
changing between two runs of ls.
