I am the facilitator for the SIMPL open source project (http://
www.icanprogram.com/simpl). The SIMPL toolkit project started over 10
years ago as a way to bring Send/Receive/Reply (QNX style) messaging
to Linux. A SIMPL application consists of two or more interacting
SIMPL modules. Those modul

A new open source project has been started with the aim of building an
open Linux framework for TCP/IP enabled video camera systems.

The framework will be layered on the ultra lightweight SIMPL toolkit

The SIMPL project (http://www.icanprogram.com/simpl) aims to bring the
simplicity and power of the Send/Receive/Reply messaging (first
pioneered by QNX) to the Linux world.

any number of languages now (C, C++, Tcl/Tk and Python

SIMPL is an open source project which has been around for almost 10
years. It maintains a very compact interprocesss communication
library which gives Linux developers the Send/Receive/Reply messaging
paradigm first popularized by QNX almost 30 years ago.
