Delta Chat for Cloud Phone

[Tombarr]

@Simon

so do the apps run on their cloud or on the device?

Apps run on the cloud, and the screen contents are streamed to the device

@Simon

So you would basically need to host a server for each user. not ideal, but can be already done today without all the work that would be required to make deltachat core run standalone in wasm in a browser.

If the server needs to live longer than a single Cloud Phone user session, then this wouldn’t be viable. It would be better to wait for a standalone Wasm binary, since Cloud Phone uses Chromium 128+ it has much better Wasm support than KaiOS.

(BTW all the building blocks for a KaiOS version are there meanwhile, I just didn’t find enough time yet to assemble them together and write a web UI that works with small screen and keypad)

If you would be interested in helping me to write a UI for such keypad feature phones, then we could even attempt to apply for nlnet funding for developing a prototype.

We could use such an UI on Cloud Phones and KaiOS phone, use jsonrpc for core communication and a runtime interface similar to how we do it in desktop:

Sharing the UI is a good idea, although Cloud Phone goes as small as QQVGA (128x160), which can be quite different from QVGA (240x320). I’ve never heard of nlnet, but ideally the end outcome is an app that’s easily usable on these devices without complex configuration or a desktop computer. For many Cloud Phone users, this is the first time they will use the internet
