So can I expect it to work with ssh? SMTP? SNMP? Or any application
I'm likely to use? Who's going to open the corresponding firewall
holes?

Either clonezilla or a minimal OS install to start. Or if it is a VM,
copy/revert an image. But except for development build systems we
mostly work with hardware.

On real hardware?

Great... Why have a firewall when holes open by magic at an unsecure
application's request?

I'd really like at least a 4-port switch and room for at least a pair
of 2.5" drives in what could still be a relatively tiny case. That
is, combine everything in a typical router, nas, and media player.
Current CPUs should be able to handle all those tasks at once.
