I start and stop the server manually. I know that this should be 
improved, but there are a few other things that I'd like to focus 
on first.

Things such as the standard library location can be placed in 
$XDG_CONFIG_HOME/dcd/dcd.conf or $HOME/.config/dcd/dcd.conf on 
Linux or BSD, or dcd.conf (in the same directory as the server 
executable) on Windows. The server reads this on startup and 
caches all .d and .di files that it finds in the paths in that 
file.

Symbols are filtered by the import statements that are contained 
in the text that you send to dcd-client, so there shouldn't be a 
conflict. If you have multiple foo backages each with a bar 
module, then it'll probably break.
