On the configuration page in nodejs plugin section (screenshot attached), when I click Add Installer button, and I select "Install from nodejs.org", I can choose which version of node.js I want to install during my builds.

It would be very handy to add a new item in the list of possible sources: "Install from iojs.org", which would list all the io.js versions retrieved from https://iojs.org/dist/ (the same way it is done for node.js).

I have checked around and it seems nobody is working on this or has requested io.js support.

Right now what I see as a workaround is to pre-install io.js on the build slave and reference it from there, or write a shell script to download the needed version of io.js as the first build step. But it looks like not a big deal to me to add io.js support (we just have to do the same thing, the only change is the source of the installations)

Is there anybody interested in this improvement? Is this really not much effort to do? I am considering of adding this improvement, but have not checked the source code yet. First I wanted to make sure that it is not in progress.
