Well, if this ever were implemented, it could always be abused. But probably no more then any conventonal weapon or ship could.
If this could be done. It could be done easily enough for us to do so without overstressing the dev team, then I would say do it. I'd suggest only mounting it on dedicated carrier class ships, and maybe having it replace the Capital armor slot. Thus meaning that Carrier vessel will have to stay back and support it's fighter screen.
The NPCs however would still probably be no match for actual players. So having your friend in a VHF protecting you would be worth a bit more then the NPC squadron, but the potential RP value is still worthwhile.
