NewPerson question about Chat server example

[Jack Park]

All the screencasts, etc, say that ChatServer is an object, a singleton.

What if you want one portal to serve more than one chat conversation
at the same time. Does that argue that ChatServer must be a class and
that you then must create a way to save the larger state (who is in
which ChatServer instance)?

TIA
Jack

In the example code, it is a singleton.  There's no requirement that it be a singleton.  Just make lots of instances of lots of chat rooms and allow the user to select the appropriate on.

The example code is distilled into the key concepts of both Lift and Scala.  It's a starting point, not a destination.  It's also the minimum number of lines of code so that developers can focus on those key concepts and so that, when I give presentations, I can type the entire application.
