well ..I think I'm still missing some bits ...
I added a Generic Web Device (with its Generic Proxy Orbiter child ) following the wiki info, I formatted the orbiter skin to fit a web pad and everything went fine.
Web pad is showing the web orbiter in the desired shape and everything is OK.
Then I repeated the very same procedure to add a second Generic Web Device (with its child as well) and formatted the related orbiter skin to fit a mobile phone.
To my surprise both web orbiters are showing mobile phone skin.
In the web browser when going to http://dcerouter/pluto-admin/weborbiter.php
I put the proper user/passwd, then it comes a page where I'm supposed to choose the proper device.
No matter which one I select, (web pad or mobile) I always get the mobile orbiter, that is the last one I added to my system.
Is this the expected behaviour, or am I doing something wrong?
