I am developing and maintaining a site for a customer. The customer will be adding (including images) / updating products and prices, and nothing else, on the 'live' site. I will be doing all other maintenance and development on my testing server, and then uploading the database when necessary.

If I upload the database from the dev. box to the live site, it will over-ride any amendments that have been made directly on the live site; it is not practical, nor desirable, for my completely non-technical customer to access my dev. box for product additions / amendments, as it is an old PC sat on my desk at home.

Is there any way around this problem (he asks, expecting the answer no....)?
