Okay, then I will try to set up a ARM-cross-compiling on my ubuntu laptop and try to write a init program. I have found several web-servers with php-support that I can run on the Central. It would be great if I could run the php-application on the Central in stead of on a seperate computer.

Support for bigger drives, could that be written as a module, or do we need a new kernel?

Any tips on setting up the cross-compiling environment?
