Okay, if my statements and yours, and the posters question, are all valid, then he should simply be able to configure FrontPage to connect to his WebDav server.
There aren't going to be any changes to FrontPage Extensions. I don't know anything about DAV except that Martynas says it's installed with Apache2 by default. If that's true, and if what you write is true, then why can't you configure FrontPage to connect? If all the above is true, then this really isn't a DirectAdmin problem. If it's not true, then we have to figure out what's not true, and add what we have to, if it's possible to add anything.
So the first step is: Is Martynas right? Does apache support DAV by default.
If not, then the next step is to add support. If so, or after adding support, the next step is to test it using a copy of FrontPage with DAV support.
If I'm missing a step, please explain
