Great news!! Looking forward ...
As we discovered playing with it on ICS, something in the gapps for Google Now Voice (JNI so's?) is armv7-only! This stuff might even be outside the realm of opensource as well
Needs a look.
Does the older (ICS) voice-recognizer work? If so, the workaround on the Google Now for ICS would work here too. A couple of widgets do the job--might need a modified Velvet.apk to use them as posted there.
If the new recognizer could be fixed for armv6, that huge (and growing with language packs!) /system/usr/srec must be stored elsewhere and symlinked. Cannot be done at flash, must be pushed and done (and redone) manually after flashing. We might need a post-flash one-time script to handle stuff like this but our hardware limitations demand it.
(I also do not flash gapps--maybe I will use the mini-gapps posted for its items if they are not already on the ROM--but install all else from play, user apps, movable or linkable. Also, anything not needed to start android, i.e. email, keyboard, browser, etc, can be made user apps and linked to sd-ext. I have 20meg, count 'em, on my system partition and only touched a few items for that. Not enough for srec, but makes experimenting/surgery much easier. When I flash your ROM, I will do the same thing--waiting for the camera and something I can stay with and play with for a few days, at least.)

Chrome is the "default browser" for JB and play shows it as incompatible with the p500. I actually have a build 14 of Chrome that I side loaded and does work on the phone. I am not impressed with it.
