I post here since we worked together for some time when Porteous was born and you could find interesting features to copy from PixieLive to Porteous, for example:
- the bootloader menu in which you can easily save your preferred settings just by copying the corresponding code in the corner

- the Encrypted Filesystem EncFS support for personal data
- the modules naming convention which allows to customize the distro by tracking dependencies just by reading the module name : Discover How
- out of the box support for nVidia Optimus
i hope these features will inspire some new ideas to make the world of live distros a better place

feel free to contact me if you think i can help you in the development
