Yes - apparently it's pretty easy to do - I was thinking of doing it but haven't found the
time yet.

any Unix process – and can deliver it to a batch processing system like Hadoop or a real-time
data store like HBase. All this can be configured dynamically from a single, central location
– no more tedious configuration file editing and process restarting. Flume will collect
the data from wherever existing applications are storing it, and whisk it away for further
analysis and processing."
