It's been developed with 0.8 in mind. Giving a quick look at how 0.7 stores data in ZK, it looks like it's slightly different and might not work straight away.
If you are intersted, have a look at: https://github.com/quantifind/KafkaOffsetMonitor/blob/master/src/main/scala/com/quantifind/kafka/OffsetGetter.scala This is where the data is read from ZK and Kafka. If you have a 0.7 setup, you might be able to adapt it to get the right offsets, you would probably not have to change anything else in the code.
