That is right.
I'd guess that the "runtime" in this case can be much smaller than
Pivot's JARs because it relies heavily on functionality that is
already built into the browser. With the exception of the drawing
primitives provided by Java2D, Pivot's UI is implemented entirely in
the platform JARs - given that, I'd say that 2MB (including debug
info) is pretty small. :-)
That is pretty small yes, but it is 10x more than GWT :)

Agree, the JRE is great, but not so great at client side. Today i
studied pivot, my browser crashed several times (FF3 / GC8) and that
is not making me happy.
