I was about to suggest “I’m curious: what about sshd?” And maybe follow up with a reason to use it or doubt it, such as “You could run remote commands through it...” Which naturally leads to “but it doesn’t pass as easily through firewalls as SSL, and key exchange is harder than a URL encoded secret...” Essentially, take your suggestion and expand on it slightly, inviting further conversation?

You could also just bring it up generically, such as: “In the sprit of an FAQ question like ‘What about X?’ I’d be interested to hear your thoughts on how this approach compares to sshd?”
