Can an explorator install a MUI interface on just about any machine given some time and effort? Is it a complicated device that is present in some very rare machines?

Is there any more information besides the description of the two MUI implants in the core rogue trader book?

Can my character have any hope to eventually fire the ships gun or a murder servitor through the said interface without some GM fiat?
