very nice article. My boss asked me to do nearly the same, he wants to launch very complicated intranet portal. Our office network is running on Windows 2003 server as well.
My problem is I want to set up linux machine with apache, php and mysql running, so I can start with building internal CMS system based on php and mysql.
My problem is that my intranet mysql database will need to be synchronized with public mysql database which is located at the data centre in town together with public client portal and server. Is it possible in some way to do the synchronization in this structure both ways?

Please let me know how do you continue with your project.
