Having extra things to charge and carry and lose is not nice though. It'd be simpler IMO if one phone streamed its music to the second, so that it's a pure software solution.
Given we're discussing Velo... the name means "bike" in French. Edit: which is probably fine.
For shape and size, why not something flat that can attach to the back of a smartphone? Size and shape of a small stack of credit cards. Give it enough battery life to last 24 hours. If the product works, then build it into protective cases for the main smartphones, maybe working with accessory makers.
IMHO, velo is a nice name.
I agree it would be easier, but we are not living in a free world. Everything is a walled garden. Sharing is pure fantasy. Everything is closed, especially on iOS, but Android is not that much of different. So Velo enables sharing outside these ecosystems.
When it comes to the name, I realised Velo has something to do with bikes, after I came up with a name. There is a story behind the name I just posted in this thread.
It seems like a matter of time before someone sits on it. It's a great idea though.
At least I see three could be very useful, e.g. for kids in the backseat if they share a tablet for entertainment on the road.
You can of course add >2 support later.
I love your input! This is why I know HN would be the best place to consult. Yo-you concept starts to resonate with me :) Thanks a lot.
The triangle shape doesn't resonate with me; I think it's really awkward. I propose something like an 'imperial' profile yo-yo (called 'classic' in the image [1]), where the two disc-shaped halves can snap together.

I think that style of design is recognizable to be snapped together while maintaining separated shape that is not unwieldy to handle and pocket. Not to mention 'velo' sounds like a plausible rhyme for yo-yo and in my opinion, sort of onomatopoeically and etymologically conjures an image of a fast and nimble device like a yo-yo.
