You can use @Intercept to set a different interception policy. @Intercept(InterceptType.INVOKE_APPLICATION) should limit interception to only occur during invoke application phase, for example. I'm not sure what makes sense in your application, but that would be one avenue to explore in the short term.
Perhaps in the long term @Intercept(InterceptType.NEVER) should be applicable to individual methods? I guess we'll have to see what Gavin thinks about this.
