Hi sbook & vade,
I was working on this for a few days last week as well with limited success…
From the jni bridge, finding and connecting to syphon servers seemed to work consistently, though calls to the syphon library from a jni function always produced loads of “__NSAutoreleaseNoPool()” errors.
In any case, I was getting garbled data on the client read and could not figure it out, so instead of beating my head on this too badly, I wish you success on making this work soon!
