I'm not _exactly_ sure what you are trying to do, but here is a different approach you may wish to consider... Scenario : Serveral "authors/publishers/whatever" uploading new/different material to a centralized source. This material then needs to be deseminated to multiple other individuals and kept syncronized. Should also have the ability to be queried for differences. If this fits what you are trying to do, have you considered using CVS? It has serveral advantages over what it looks like you are doing now. 1. It can be fully automated on all sides. 2. It keeps track of everything that happens. 3. It can be tunnelled through SSH for added security. 4. It works. (don't be fooled by the programming thing, it really does work well for binary files as well) Just a thought. -- Brian Ashe CTO Dee-Web Software Services, LLC.
