I0coin is still on the list of projects, it has just fallen down a "few" rungs.
If somebody does not fix it before I can get to it, I promise to take another look at it.
I the mean time, if someone could post a 64 bit executable for i0coin v0.3.25.9 it would allow more miners to keep it alive! I had to stop mining once the 32 bit version died.
