Late last week I released 2.0.1b, with a bug fix (bug #5) in the rxadm admin tool and a few cleanup changes in some of the module print messages. More details can be read here: www.rapiddisk.org
I have also been working on an ARM based Linux distribution called RapidDisk LX which brings RapidDisk functionality as a SCSI Target. More details of it can be read here: lx.rapiddisk.org
This distribution has already been listed in the waiting list at DistroWatch.
