hi Herkules, bmyers
on larger platforms (PS2, PC etc) a code lib is included in the SDK and this is C++.
For mobile Terraplay utilises a protocol model where developers code towards it, allowing a small footprint which is difficult to achieve using standard APIs etc.
The SDK today supports any language provide the protocol is followed, but the examples are in C++. The extension which is coming is for http as a bearer, and yep that is aimed primarily at Java. However some phones support TCP from the JVM today.
If you want to look at the sdk and model please drop me a line email@example.com
