Good time of day!
I would like to know if there is a source code available for HFS,
if not, would it be possible for a developer to cross compile HFS with winelib for ARM CPU so that devices like PogoPlug SheevaPlug etc. could run this awesome piece of software. By the way these boxes are pretty powerful running 1.2 GHz ARM with 256-512 RAM and are only about $50 to buy.
Before you say it's impossible, please read the following
http://wiki.winehq.org/ARM.
PogoPlug, SheevaPlug and so on run Linux natively (Iam running PlugApps linux). I have wine compiled on it but of course I can't use any windows software since it's X86. On the wine wiki page I provided it says that it's possible to compile a windows application with winelib for arm to use it with wine.
Also, if this interests the dev, I'm sure the man who worked on wine arm, will be glad to help
