Well, there might be a few more specific questions - eg, regarding file names and directory names.
(1) What if the daemon for Bitcoin Classic has a name other than 'bitcoind'?
Currently I don't think armory can handle that, but this scenario is unlikely.
(2) What if the home directory for Bitcoin Classic has a name other than '~/.bitcoin/'?
The data directory can already be changed, so this is taken care of already.
Or perhaps the user could simply rename the Bitcoin Classic filename / directory name to match the Qt names?
Could do that
Or perhaps Bitcoin Classic will actually be released using the same names that Qt used?
That will most likely happen. It is a fork of Bitcoin Core, which already uses bitcoind; there is no reason to rename it.
