Problem with URL keys

[Stéphane Miousse]

When more than one site is installed on the same jahia instance, URL 
keys are global to all sites. So if 2 webmasters out of my 5 total jahia 
sites wants to give the URL key “home” to the home page of 2 different 
web page, it seems to be impossible. Jahia gives a message saying that 
that key is already in use. Is there any current or incoming 
devloppement for solving or avoid this problem?
