[ubuntu-art] Quick user switching panel applet. OT?

[Sumit Chandra Agarwal]

I'm not sure if this is quite on-topic for the art list, but it has to 
do with visual presentation so I thought I'd try here first:

As it is the top panel in Ubuntu is as cluttered or more cluttered than 
Windows or Mac desktops, with the addition of another panel at the 
bottom. One item that is significant taking up a lot of space on the 
upper panel is the fast user switching applet, which manifests itself as 
text showing the current user name.

This is a great feature. However, I would *guess* that for greater than 
50% of Ubuntu users this is unnecessary as they are using the machine as 
a *personal* computer and as such they are the only user registered on 
the system. This makes the applet pointless and it only adds to clutter 
and eating away at space.

Could Ubuntu be configured to intelligently only add the applet if there 
is more than one user registered to the system?

Sorry if this is off-topic,
