Correct me if I'm wrong but a delegate's job is to sign messages. Nothing less, nothing more. A cell phone could do that. My point is a micro instance can totally do it, and it costs like what $15/mo? AWS instance would be much more likely to be always on, compared to my home internet, which goes out once in awhile.
Another reason I offer AWS is because it is extremely easy for someone to create an image, that then others can just fire up, may be edit a single file and reboot. This discussion is about bringing non-technical delegates on-board. Even if it is just 5 lines, it's never that simple, unless you use the exact same version for everything. Even then, sometimes you do an update and you get the wrong library linking mixed up, stuff doesn't compile. I'm advanced user so I can recover from these things, but it is very discouraging for the non-technical fellas.
