I was going to suggest "Pyrana" as a joke since some of these names include "Pyra" in them. It turns out that is the name of a weapon in the game Warframe, which is a console and Windows game, so maybe we should skip it.
I still like Funeral Potato. I will look for some more game related ideas.
I would argue that there'll be more than just "a few scripts" to differentiate it. If I've learned anything from the Pandora regarding the OS it's that it will be almost certainly be significantly customised over time.
Off the top of my head though....
The DBP system comes immediately to mind.
There will probably be a DBPManager developed and included somewhere along the line. (possibly as a fork of PNDManager)
I rather suspect FunKeyMonkey or something similar will be integrated to manage the input devices.
Perhaps there'll be a version of bsp's c64tools to manage the DSP. (the OMAP5 does have one after all even if it's not as full featured as the OMAP3 DSP, maybe it will even be used for more than one application, who knows)
There's also any Pyra specific UI stuff that ends up getting implemented, like the Pandora's Config-button which could be used with Pyra specific plugins.
Plus any number of other differences I haven't even thought of.
