Yes I use remotedsl with no problem. i'm using admaster. You can easily change IP every 2 minutes adn the good thing is that it change mostly whole ip, not just last 2 sections of ip. You can easily use firefox and refresh addon to refresh every 2 minutes. It's better than using macros.
Im alos using as im in the u.k works great for me with admaster, also ask george to hook uyou up with a macro to change the ip, also make sure the screensaver is set to a long time otherwise this will mess with the macro when it comes on.
i setup a server in my office that does the same thing as remote dsl. i have my posters dial in and they can remotely reset the ip. I am on qwest dsl and it changes about the whole ip as well and is working really good.
