I can’t nelp with specifics, but the first thing folks need to know before pointing you in any particular direction is which NAS server do you have? They vary quite a bit, and some will be much easier to set up than others – and some will already have suitable software included or readily available.
I looked around a bit on this, and I don’t see anyone having made any announced progress on hacking this.
Before arbitrary software can be ported to a system like this, the first thing that someone has to figure out is how to break into the machine to be able to install software (and potentially make replacement firmware).
Nobody seems to have done this yet.
I don’t even see a web site yet consolidating hacking attempts. Either it doesn’t have a large user community, or it’s so recently released that nobody has really gotten a chance to hack on it yet.
In either case, it looks like it will be a while before you’ll be able to run arbitrary binaries on it.
