Hi,
Part of GWT/GAE book, I've just added a chapter on RESTful services:
http://code.google.com/p/gwt-gae-book/wiki/ManagingLocations
Looking forward to group feedback and better ways to consume REST
services from GWT.
Happy New Year :)

The protocol self seems to be pretty save.
But with webapplications you have the problem that the algorithm using

Therefore, you must guard this JS via SSL or it can be manipulated

You can implement a java Filter in the server Side and check if the session
is valid
if is not valid yo do the redirect in the server side.
you can use that way if you call a normal resource to the server for example
a .js or img or .jsp or html
to use it for a RPC call you must
context.getAllAs().with(bs, bs.c)
(the bs isn't required actually, you can use bs.c only, but then you
might not have other fields of BProxy --haven't checked--, and I find it
easier to read and understand with both bs and bs.c)

You can use @ImageOptions values in UiBinder using the flipRtl and
repeatStyle attributes of ui:image (e.g. ui:image field='foo'
repeatStyle='Horizontal' /), but note that no-repeat (RepeatStyle.None) is
the default.
As for the color, maybe try a separate background-color:#DCDCDC property.
