How do I run Armory Testnet on Win7 x64 using Bitcoin Core 0.9.3 using remote datadir?
I'm going to answer my own question for those interested in the solution: 


Armory and Bitcoin-QT use confusing switches; Armory going for the --flag while the latter uses the -flag
A remote Blockchain directory is identified using --Satoshi-datadir= while -datadir= is used with Bitcoin-QT
Ensuring the Bitcoin.conf file is correct is the main issue. Correct values required are: listen=1, allowip=127.1.1.1
