Hi,
I can help you build a website for speed testing using HTML(5), CSS(3), JavaScript and PHP. This website can be used on almost modern browsers, even on smartphone with JavaScript support (iOS, Android, Playbook...). This web tool can help you measure the connection speed between your computer and the web server where the code is placed in.
If you want to implement this web tool to several servers, I also have the solution for you.
No Flash, Just Web.
Please visit my portfolio for demo.
