FTP Server and Updates, a little bit OT

Hey, i have only a little point which i can't understand. In my local LAN i provide a FTP Server with the the Suse install dirs to easily install other clients with Suse. To always have the most up to date binaries i mirror the changes from a mirror-Server of ftp.suse.com (the update dir) Are there problems, if i copy the update rpm's directly into the "ftp install hierarchy" ? And if there are no problems, wouldn't it be better to handle it also on the public ftp servers ? I know it's a little bit OT, but everyone want the newest and more secure software as simple as possible. Sorry for my english. Greetings Torsten
