I am looking to possibly get a pogoplug device, but had a question concerning it. From what I can tell, files are accessed through the pogoplug website for outside your network and from any internet connection. Is this correct?

Is this also the method for accessing files locally over my own home network? Do things have to go through some sort of PogoPlug software and/or website for home retrieval?

I am basically concerned that if Pogoplug goes out of business, will I still be able to use this product and simply map the device or use software on a local PC to gain access to files over the Pogoplug.
