That was kind of what I was thinking.
As a VERY minimum, you need to be sure the previous rsync is not
running when the next one starts, so the fast cron job either
needs some careful work done to insure that, or you should change
it like Dave suggests, or perhaps do the right thing and get
some kind of remote mirroring set up.
I did a search on freshmeat, and these look amusing, anyway:
http://freshmeat.net/projects/rsynchelper/
http://freshmeat.net/projects/yokelinuxkerneldriver/
http://freshmeat.net/projects/pushsite/
http://freshmeat.net/projects/mirrordir/
http://freshmeat.net/projects/drbd/
The first one is an rsync helper app, which may or may not be useful
for what you want to do. the others (especially mirrordir and drbd)
look more like what you want, maybe.
Good luck!
