Remotely Anywhere
I just recently switched to a new program called Remotely Anywhere and what it uses is Active X, Java or HTML to remote into servers using a web browser. I've tried using it on my mac that's using all updated Tiger 10.4.3. But, Safari hangs like it's loading and the tool doesn't load up show up with the desktop.
