How long-lived do you need those connections to be? I don't usually run my 
laptop too long without rebooting (rolling distro, kernel upgrades), but 
sometimes I can go up to a full month. No connections break. On servers, 
connections to systemd via D-Bus can last years.

There's no problem with the length of the connection. Just don't send invalid 
messages that will get you kicked out of the bus. That hasn't been a problem 
for 16 years.
