Fore those interested I have uploaded the KnJ Prototype chapters to my mediafire account:
KnJ Prototype.7z
Since other folks don't feel like sharing I suppose I'll just share some more stuff that I have found.
[Nipponsei] Kodomo no Jikan Original Soundtrack.zip
Kodomo no Jikan Nigakki OP Single.rar
If you are having trouble with the .7z file you can go here to get the app that can open it (hooray for open source):
7-Zip
I'd also encourage other folks to share their own KnJ goodies.
