so I set up a 2nd server according, somewhat, to these instructions, except that again I simplified, and used rsync to transfer the already-built bitcoin sources to the new droplet, and scpd over my bitcoin.conf as well.

then, according to the getblocktemplate docs, I wrote mine.py, but it doesn't work, giving me a KeyError: 'coinbasetxn' on the returned dict. so I have some digging left to do, perhaps a lot of it. and I haven't even had to deal with the segwit stuff yet, since the regtest server doesn't seem to require it, or perhaps even support it.
