If you look a bit further back on the list archives, I was recently
wondering about setting up a user bus type, with a per-user socket. This
has possible security issues which concerned Havoc, and he didn't seem
quite conviced there was a use case for this. This is a different solution
for a similar problem, although I wonder if it's just overcomplicating
things. What's your use case for this? Would it be sufficient to add a new
bus configuration file which set up another uniquely-named (a-la-session
bus) socket, and then registered the names with a user bus registry on the
system bus (bus station? :D).
