software distribution

[Doom9]

does anybody know of a simple solution for software distribution over different ftps? With all the different webspaces it would be nice to upload once to a master server and start a script there that would connect to the other sites, and synch the 2 servers (upload what's new, delete what's no longer on the master server, overwrite files that are newer (based on size and creation date)). The solution should be platform independent and preferably something like cgi or php that wouldn't require extra work for my admins.

one simple solution would be just to use fxp capable ftp client, such as FlashFXP.
connect to 2 sites and transfer stuff from one site to the other directly, bypassing your pipe.

I already do that.. but there's 2 problems: 1) you still have to set it up manually, and 2) not all servers support fxp.. strangely enough my latest unix server does not like fxp at all
