Is there any guide or info related to how to use ArmoryDB with a remote latest version bitcoind?
Not possible atm, ArmoryDB needs local access to the blockchain files. ArmoryQt does not however, i.e. the db has to live on the same OS as the node, but the clients can access it remotely. There's a plan to allow the db to connect to the node only over a p2p socket. Not a priority atm though.
It *might* be possible to export bitcoind's data folder as an nfs mount on one machine, and mount it on a second one... I haven't tried this, so i don't know if it would work.
Won't work, can't mmap files on network drives.
