I think this is possible provided you create your own DBAdaptor subclass.

I think this is already available in Cayenne 1.1, using either JMS or
JavaGroups or your own implementation.

If you're already working at the graphics "assembly" level, you might
consider something like jME Graphics Engine. It's a 3d rendering engine
based on OpenGL, and seems blindly-fast for the things I've used it for so
far. There's also some 2d support -- not sure if there's enough in there
for you or not.

Or you could skip to one of the underlying rendering systems like LWJGL if
you're comfortable programming OpenGL directly.
Or going the other direction:
I'm also including a forwarded message by Martin Cooper of Struts on writing
thick gui-rich web clients.
I don't think "Flex" is mentioned, but since you're doing Flash stuff
perhaps that's a good fit since it's also a Macromedia product.

We are currently using two different frameworks (together). One is
commercial - Isomorphic SmartClient - and one is open source -
nWidgets.
SmartClient has a highly sophisticated widget set, and runs on just
about every browser since Netscape 4.5. They essentially built an API
layer on top of the browsers, and wrote everything else on top of
that. Some of their widgets would take huge amounts of work to
replicate, which is why we use them. ;-) We also use some server-side
optimisation stuff that comes with SmartClient, and that helped hugely
with our performance optimisations.
nWidgets is a much smaller, leaner framework that works on top of /
along side the browser DOM. As such, it doesn't support older
browsers. The widget set is mediocre, but the underpinnings are very
powerful, and it's those underpinnings that we use it for. For
example, it has some really nice mechanisms for partial page refresh
that we use extensively.
One thing to bear in mind is that SmartClient is huge. They used to
package it as a single 600KB .js file, which obviously has serious
startup costs. We are now using a broken down version, where we can
load only what we need on a give page, but I'm not sure if that made
it into their product, or is custom for us. (We are probably their
biggest customer.) nWidgets is much, much smaller.
There are other frameworks out there too. The one to watch is Dojo.
This is being put together by the brains of all of the high quality
open source frameworks, with the goal of pooling all of their
knowledge and coming up with the ultimate in client side frameworks.
These are a bunch of very smart people. (I know because two of them
work for us. ;) However, their goals are lofty, and I'm not sure when
Dojo will be ready for prime time. Other frameworks that I'm aware of,
but have not used, are Burst and f(m), both of which are open source,
and FacesClient Components (nee Odyssey Browser Framework) from IBM.
