Currently I have a free 1 TB cloud service at my disposal, and I never use it simply because uploading is too slow. Most home users will have this limitation. Downloading is much faster.
Then those who do upload are going to make some serious BTC in referrals. Which would inspire others to sit around in upload tedium in the hope of making money too.
As there are already lightning networks being played with, I assume this is similar in principle. But perhaps there is something super new. Regardless I don't really know how they'll get all these users on and off their side chain with the proper chain as it is.
