Silent Install? Can you, will you be able to?

I would like to Silently install Firebird onto a number of PCs as part of
the default build. I've tried using a number of switches (-ma &/or -ms) and
changing some of the config files:

setup.ini
    [Netscape Install]
    silent=true

But it still asks for confirmation about the install location.

Is this something that it supports?

Are there any plans to support this?

Thanks,
