@mficzel seems to have found the option that sounds the best to me.
Neos.Fire feels better than Neos.Pipes or anything else suggested here.
Then we’ll have Flow, Fluid, Fire, Eel (If Eel had a logo it would have to be an electric eel), Fizzle, FlowQuery, Media, and TYPO3CR.
To make TYPO3CR fit with Fluid and Fire, maybe we could call it the Neos.SolidCR (liquid, gas, and plasma are all fluid states, so that leaves “solid”, though Neos.PlasmaCR has a nice ring to it as well). Content is very substantial after all 
. But this is off-topic…
