I don't know why he would be unable to download the source code. Rapidshare has been making free downloads more restricted of late (based on time of day), but the source code can still be downloaded normally.
It's true that I have seen complaints about the lack of a changelog and source hosting only on Rapidshare from tech-literate people (I bring up Iron in Chrome related stories on Slashdot
)... could the source be hosted on Sourceforge instead?
This would give Iron a more positive image among nerds...
