Toolkit... I agree, this may put it across as "yet another parted-magic" or something like that. Sure it can be built up as such but parted magic or other toolkits are sort of stuck in one configuration whereas tinycore is far from it.
May I suggest it be pushed as a fully modular distro, as powerful (or really, more powerful!) than your typical bloatware distros, but completely customisable for your own needs?
