Old binary packages.

I am looking at the possibility of cleaning up the binary tree on the ftp 
site, and was wondering what the group thought about purging old binaries.  
What I was thinking would be to remove all but the last minor release of each 
major version.  Thus, I would remove 7.4, but leave 7.4.1.  The space taken 
by binaries is significant (about 1GB at this point).  Since we are keeping 
all source releases (although I would question that, since we use CVS), 
keeping all the binaries around is just a space waster, IMHO.

Comments?
