I have CustomSerializers for the JTS Geometry classes (they don't have no-arg constructors), which seem to be as efficient as they can be (write all attributes on one side, read on the other) and on the client I wrote simple lightweight versions of (some of) them to be emulated. I was actually thinking of doing the Polygon "union'ing" on the client for the BoundsCache. I'm just not sure how good this idea would be.
And thanks for the tip on the gwt-google-apis Maps implementation, I forgot to mention that I'm already adventuring with gwt-google-apis trunk version + gwt trunk's version as Mapitz apparently is not being developed anymore. It might be a lot of work, but surely it is fun, wish I could earn a living doing this. When I get my BoundsCache, I'll post it, it is only project at project stage at this time.
