Ok, building a stub here...
someone found an unrar binary for the box. take a look here:
scroll down a bit to find dropbear and unrar binaries.
i tried this on a argosy hv359t wich essentially is a screenplay pro, but got following error:
~ # unrar unrar: can't load library 'libuClibc++.so.0' ~ #
so, could one of you try this on his screenplay pro? if it works, i would try to make some hybrid of my and the iomega firmware to get it running on the argosy device.
EDIT: ITS DONE. i found a suitable uclibc++. if anyone needs it, please let me know.
the box is now able to unrar its torrented files... =)
in fact, unrar dumps the core after unraring all files. but this is better then nothing...
EDIT2: have a look at the comments. there is another unrar binary, wich only dumps core when called witout arguments. when called with a file to unrar, it works neatly.
