Oh yes indeed. A physical connection, Drone or RC would be an option to achieve this. (Though I'd prefer if you didn't all just happen to have one in your pocket - and if you do come up with a reason you'd have used it before and all of that kinda good stuff - or of course try to buy one). 

Of course the Hackers could work together, or oppose each other. After all, they don't know if this is a competition or not and how many 'spaces' Dedsec are looking to fill. 

You could try to contact Toxic to ask such things, but that may or may not work. I like to give infinite freedoms in terms of opportunities and ideas you may have - as well as the methods you may choose to do things. 

Generally if you're not sure about something then just ask. Also I know practically nothing about Hacking, so as long as it sounds cool and about right you can make it up as you go along. Just please try not to be too OP and just hack everything easily. 

I'll let you do whatever you want as long as it makes a good story, after all, that's why were all here right? :)
