Judging from the information provided here:
http://storj.io/earlyaccess.html I imagine the test phases will be complete sometime around March 2015... But there is no fixed deadline.
Right, I just hope that this project succeeds and not get dropped halfway through. Need a cheaper way to store my files

Yeah, we all hope this will succeed! And considering the progress done so far I think we are on the wright track - it might make some sense for you to also invest in some SJCX

If this will be a success, we can expect for the price of SJCX to increase substantially!
Also this won't just be a cheaper way to store your files - but a much much safer and secure way!!
