That's interesting!

I'm just not sure the "security" of WhatsApp is preserved in that case but it's certainly better than not being able to talk to certain people at all.

Also I think these kind of meta chat apps have been tried before and it usually doesn't end very well so I'm not sure I would be super optimistic.

Any of the chat provider can break their link to beeper and since they probably don't really care about it it shouldn't very reliable.

But a cool find nonetheless!
