The Perfect Distribution?

Q-tip writes, "After researching the various major distibutions, I have come to the conclusion that none of them really stack up to what I want, so I'm wondering just how much work it would entail to create my own Linux setup from scratch. I imagine it would save quite a bit of time to reuse and heavily modify the startup scripts of another distro, but what else am I overlooking that could be a major hangup? " We've talked about creating Linux distros from scratch but Q-tip is looking to make derivatives of existing distributions. Any helpful suggestions?
