Hello all, I am new to this list and to ZOPE and before I dive into documentation and start banging my head against the wall I will ask for your advice first. Here is my problem: I am in charge of building an application for a real estate company. The purpose of the application will be to manage all the data (Properties,clients ...) of the company. They have 4 offices scattered across the country, all offices have a dedicated connection to the Internet with a fix IP. They also have a web site and it's necessary that the changes in the data reflect themselves on the web site (the data on the web site is a sub-set of the data in the offices, e.g: they don't have client information in the web site, but they have information about available houses to rent). So my question is: For what I've seen of ZOPE it would be trivial to make the application and install a copy in all four offices, but is it possible to synchronize the data between all four offices and the web site? Also, they are thinking of opening a small office with a dial-up connection (dynamic IP); would it also be possible to put this office in the equation? If so, can anyone point me in the right direction? Where should I look for information about this? Thanks, Luis Neves
