I'd have to agree with andreas1234567. rsync or rdist are the way to go. You don't say what type of server you're load balancing but I'm going to assume web servers. If that's the case, you should chose one machine (and probably not one being load balanced) as a *staging* server. You would then promote from your qa server (you do qa, right?) to the staging server via whatever repository mechanism you have. Once the files are on your staging server, then you rsync or rdist out to the your load balanced machines.
