If I understand correctly, the input framework is the way that log files,
for instance from a host, can be ingested by Bro?  One of the things I was
interested in doing was identifying key information from a log, such as a MS
Windows Event log, via event viewer to syslog, with network traffic.  This
would be similar to how Bro can analyze SSL Certs.  

What I was wondering about was what could Bro do with a filesystem beyond
log files?  An example on a MS system would be identifying the last run time
of a file via prefetch data that was communicating over a socket, that was
identified by Bro.  Of course this is assuming that Bro has access to the
filesystem of the system in question.

How are you looking to use it?  We have the input framework in 2.1 for
reading from inputs that we have plugins for (essentially only Bro logs and
text files right now).  We may have quite a bit more functionality regarding
that in 2.2.
