With the new 0.9.0 bitcoin core we now have an option to run without a core wallet with: -disablewallet option. It would be nice if this could be added to Armory soon! A custom options text entry would allow future quick changes to commandline in "Expert" mode...or something

Thanks for the great app.

EDIT:

I found you can also add the following to the bitcoin.conf file:
disablewallet=1
