Needless to say I am looking forward to the new promised by roberts...
My two cents on the terminology discussion of what is base:
Although 'base' has been defined by roberts from the very beginning as the minimal core TCL, and any additions are extensions on top of it, I would rather name it 'Core' of TCL, instead of 'Base', since it is pure minimal TC infrastructure, from which all starts evolving.
IMHO the terminology outlined by danielibarnes is practical for users, since after users put together basic infrastructure they need on top of TCL Core, such as Xorg, Openbox, Wifi, Browser, etc., and hopefully manage to 'remaster' or set up on usb, such laboriously put together system becomes a 'Base' for them, or call it 'baseline' from which they continue with additional fancies... SliTaz calls it 'flavours', unfortunately...
