steam multi user

[Jidea]

I play with steam on fedora 17 under gnome 3.

i tried to use steam on a multi user computer. and i find some caveats :

• /tmp/dumps can't be use by others users, because of the permissions of some of the files. (can't we use an another tmp directory for steam ; /home/user/tmp would be cool)
  
• there is some semaphores that must be removed before an another user can launch steam. when we quit steam, can't steam remove the semaphores used by the application

i can't play steam with 2 system's user without rebooting. for now the 2nd launch of steam give me this error , after removing /tmp/dumps and removing semaphore from the previous user with ipcrm :

Code d'erreur-102

Impossible d'effectuer la connexion au serveur : il se peut que le serveur soit hors-ligne ou que vous ne soyez pas connecté à Internet.

it's funny because i authenticate before the error message.
if i find a solution i will write it here.


PS: I was too quickly and did'nt test steam on my browser. steam unreacheable on the browser too, then it is not a steam bug or trouble. sorry
