I really wish there were some write-ups for doing wifi-p2p aka wifi-aware (the wifi alliance's proprietary branding for it) on Linux! Incredibly sad that it's just so so so undocumented; such a neat sounding suite of capabilities.

Haven't looked in 2-3 years, but found so little ehm last I looked. Very dismaying. So many folks doing "p2p" file sharing apps, but generally they assume you have setup networking already. We really need to own the means of connectivity. Especially now!

Unfortunately I believe it requires your WiFi firmware have the ability to switch channels with microsecond timing precision.

That means you couldn't do it with off the shelf WiFi hardware.

You might be able to do it whilst dropping existing WiFi connections during the transfer.

I'm fine having a second wifi card for wifi-p2p on Linux. Ideally the situation gets better over time, as wifi-p2p becomes a better used better travelled system.

Ideally the second wifi adapter could be USB based! For years usb cards were very second tier; I haven't tried again lately but I assume that's still largely the case.

Given that there are some pretty affordable (below $70) barebones thunderbolt docks for GPUs, it'd be neat to see some thunderbolt docks designed for one or multiple wifi cards (or other m.2).
