Hi there...
I am a brand new user of this project and I have to say I appreciate it very much.
I do have a suggestion I hope you would think about. I hope at some point to set up a Raspberry PI as development server. Since XAMPP is built for situations like this and the PI could turn out to be such a great way to put together a quick and easy server, I really hope that XAMPP eventually puts together an ARM version... maybe even something specifically for the PI, though maybe not as I think small ARM servers of all types could be a great thing for web developers.
I have some knowledge of Apache, and I understand that ARM builds of it are a little bit of a pain, but I still thought this was a good enough idea to throw out there to the community.
