If I understand you correctly, then apart from the kernel-level implications of zero-copy reads, such a facility to bring bytes into the JVM without a copy has existed in the JNI spec since Java 1.4. http://java.sun.com/javase/6/docs/technotes/guides/jni/spec/functions.html#nio_support Note that this is an optional part of the JNI specification. So some vendors may not support it. Isn't this how org.apache.tomcat.jni.Pool is implemented? -karl
