I would love a mobile application for the game for my cell phone. It would act as a character development tool.
You would only be able to load your main characters and their current ship. You would also only have access to their current equipment loadout and skills, but you would be able to acrue experience points and energy credits for that character by playing simplified ground or ship missions. You could even get awarded limited drop items that you could then access by logging onto your regular account on your home computer. You could even have limited pvp arenas or one on one battles. You could even gain experience levels but you would still have to log onto the regular game to get rank promotions. (ie. you could do any amount of levels on lt but would have to go to regular game to get promotion to lieutenant commander.) The missions might even contain mini bosses to fight and get rare items according to your performance.
