To be honest, there are too many leeches. Everything that is currently free should be $0.99 so that leeches, aggregators and other social rejecta may not collect them for "future use" (nor brag about "having" them).
Nothing that is free is respected today.
That being said, I follow this thread for a while.
It is possible I've given out hints or even stuff, if I were to do this with open source tools.
Sadly, the signed firmware and partitioning the EFS requires approaches of the official utility.
Now giving it out in a patched/modified manner would be pretty much illegal everywhere.
If someone were to reverse it, to provide for EFS handling, it would be cool - but I don't see that in the foreseeable future.
It was even unfeasible for me for the two or so cards I had to process like half a year ago.
