Kai, you asked a well framed question on an interesting topic. I should have said something more like
"No there is nothing like that currently available"
If I could type one word I could type nine. I won't give single word answers in future.
However to answer your follow up question in detail (turn on humour button)
Are you saying that no free software is available?
No (there is no free plagiarism software available)
Are you saying that nothing like TurnIt-in is available?
No (nothing like Turnit-in is available)
Are you saying that plagiarism software is not available for 2.6 Moodle?
Well you didn't ask that, but the answer is Yes, but you have to pay for it (and I have not been that impressed with what I have seen so far).
