So I will look forward to install a SPR masternode on one of my raspberry Pi's then, and run it from my home?

If I understood you correctly we come closer and closer to one day have our masternode INSIDE our wallet? Having them both be the same thing if a person desires? (Another person might desire to run a big server why not)
You can run bitcoind on a pi with a bit of effort but spreadcoind in Masternode mode is going to have a shitload more overhead, I don't think a pi is going to cut it. Plenty of better spec'd cheap little SOC boards out there though.
And a Masternode
is just a wallet with some linked collateral, I regularly use a wallet that happens to also 'be' a Masternode.
