"omniNotify offers asynchronous, decoupled, event-based communication between distributed and heterogeneous applications."
"ominiNotify was developed by a group of researchers at AT&T
Labs in Florham Park, New Jersey. Our main design goal for omniNotify
was scalability: we wanted a service that scales well w.r.t. both
number of connected consumers and number (and complexity) of filters
registered by consumers. To achieve this goal, the implementation
exploits parallelism during filter evaluation and dispatching of events
to consumers."- goto
