For reason's known only to myself I am going to configure my Nexus 7 to run multiple ROMs (side-by-side).
Of course, advice is appreciated but I will report my results back to the forum in the next 48 hours.
Unless of course, I brick my device...then I will deleted this thread. By the way, that is a benefit of being a forum moderator so if you are interested in having such vast powers please drop me a line.
I used this a few months back myself...check it out as it is a fairly concise reference. Oh, and Good Luck!
