Comet Q works well, if the usb c port supports DP-ALT

That looks like an interesting device.

I'm more talking about being able to attach a normal laptop to another computer though, without any IP/Networking requirements.

Sipeed has such device https://wiki.sipeed.com/hardware/en/kvm/NanoKVM_USB/introduc...

Cheap 4K HDMI/VGA-to-USB input boards and reverse HID cables are available. Betwen the two for $50 - they turn your laptop into a Moniitor, Keyboard and Mouse for a random computer.

where?

Can you share how the discovery worked?

This looks nice, maybe make free more prominent on the site.

I'm thinking of installing a blank bento for users as a pwa (using browser install site as app), script the author name etc and then make the file read only so they are forced to save as, for users to use as a standalone powerpoint tool.

Maybe you can implement this into the project, a blank default read only (except author details) that installs as a pwa.

I thought about make it a PWA, but I'm still on the fence about hosting in general. Will probably have to host in order to deal with enterprise use-cases, but I just want to make something simple and cool for now. Thanks for the feedback, will explore a bit about what people will want in a hosted solution and how it can keep these principles I think makes it special.
