Fwd: User bus conclusion

[Thiago Macieira]

D-Bus community is proposing to do away with the session bus and replace it 
with a user bus. Long story short, this means that multiple logins of the same 
user are not allowed by construction.

Is this something we allow or even support in KDE?

My first reaction to Ryan's email was to say that we do not want the new 
feature. Services like KWallet would show the password dialog in possibly the 
wrong X display, klauncher-launched applications would show up in the wrong X 
display, etc., so it would be unusable.

However, on second thought, I came to the conclusion that running two 
instances of kwalletd would be a problem of itself: the two wallets trying to 
have write access at the same time could end up stepping over each other's 
toes, causing data loss (one of the instance's changes or, worse, all of the 
data).

So I have to ask again: do we allow or support multiple logins of the same 
user, on the same machine (same $HOME)?
