ECho is an event delivery middleware system developed at Georgia
Tech. ECho is distinguished by efficient and flexible support for
event typing and the ability to assign event handlers to specific threads for
transparent support of both inter- and intra-process communication. ECho
also introduces the concept of a "derived event channel." ECho uses dynamic
code generation to implement derived event channels and exploit their ability
to move user-level processing to remote locations.
ECho is described in the
The ECho Event Delivery System
ECho's supported platforms include: Sun Sparc SunOS 4.1, Sun Sparc
Solaris 2.x, x86 Solaris 2.x, SGI MPIS Irix 5.x, SGI MIPS (32 and 64-bit)
Irix 6.x, IBM RS6000 AIX 3.2, x86 Linux, and x86 Windows NT.

users guide for ECho.
ECho source is built into the DataExchange
release. The derived event channel support is not currently being
distributed, but will be available soon.
Users within Georgia Tech can use full derived event channel support.
Please see this document
