Okay, sorry for the double post but this deserves it.. I think.
I did a completely fresh install of the Rooted 2.1 v0.8T2 linked to above. I saw in recovery that it wiped data and cache before installing.
Upon first boot, I was presented with a pop-up asking me which home screen I'd like to use, and Nexus Launcher was an option!
This would lead one to believe that it was included in the ROM, except that my email and applications were all preserved and working and this, in fact, was not a fresh installation as it was intended to be.
edit: Widgets were out of place, as expected, but all applications and my mail accounts and emails are preserved.. how does this happen? I wiped manually, and I saw it wipe data and cache upon installation..
edit2: Okay! I was giving up, and decided to re-install that 'Rooted 2.1 v0.8T2' again, and this time it presented me with the setup upon first boot (last time, it just booted up like the phone had been restarted). All of my customizations and email accounts are gone, but Nexus Launcher and Live Wallpapers are still there lol.
Ivan mentions nothing about having Nexus Launcher and Live Wallpapers installed by default in this ROM, but he also says he didn't have time for a full walk-through.. so I'm going to assume it's in there by default at this point.
