Is there a way to choose where to store hosted files? Will this be included in future releases? Thanks!
I am sure something like this will be in future updates. It would be cool to be able to get the wallet working on a Raspberry Pi with multiple external USB Drives hosting the storage. Would save money on electric and wouldn't tie up your main computer. I've never tried it, but I would assume you could merge all the external drives into one LVM. You could pretty much go crazy with storage and Linux. Linux makes me feel warm and fuzzy.
I am to understand that Windows 10, which is due to come out in a month or so, will run on a RPi 2. The RPi foundation has been collaborating with Microsoft to ensure this is going to happen. This means that what you're saying, having a RPi with several usb drives attached is possible, if Sia allows you to specify where to store the data. I believe at this point it's not really possible.
