if i just use cron to call rsync every 5 minutes or something, is there any
chance of conflicts?
as in one process hasn't finished when the next one begins
are there any known issues with just calling rsync in the cron job?

i can setup the server to go through ssh without using a password

also, i know that this is an rsync mailing list, but have you heard of 
any software that does synchronise files on two servers as a service?
