Hi Brian,

In addition:

1) GWT RPC is heavily optimized for serializing java objects between
client and RPC remote servlets so it will almost certainly be faster
than your JSON equivalents
2) All the serialization/deserialization work is done automatically
for you so your return objects are handed to you on a plate ready to
go. If you are passing complex object graphs (including Collections
etc) over the wire this a big advantage.

If you have a Java back end it's a no brainer really.

regards
gregor
