That's exactly why the system bus is recommended: there's only one of it, 
whereas there are multiple session buses if you have multiple sessions.

If you need to emit a signal from one user to another via D-Bus, your 
options are:

1) setuid() and connect to that user's session bus (whose address you must 
obtain through external means)

2) connect to a private connection (whose address you must obtain through 
external means)

3) send the signal over the system bus (whose address is well known)
