GPL-less alternatives to the Audit Userland

For a while I've been working on a project that ports/forks Audit to the Android platform (https://github.com/nwhusted/AuditdAndroid). I currently have a proof of concept in operation and I am working on getting the relevant kernel code back-patched and the userland code integrated in Android. One of the primary issues raised at the moment is the Android Open Source Project code base is not compatible with GPL code. I am currently unaware of any userland audit interface that is not under the GPL. I was wondering if anyone on the list knew of any, if they even exist? Any information is much appreciated.
