I've attached the extension as far as I have it ready. It uses an Object Oriented approach to talk to DBUS Objects like a PHP Object and supports at the moment calling methods with support for most datatypes (bool, byte, string, dict, all int types and double) for sending, and single scalar types for return values. It also supports waiting for signals with single scalar return values. I'm planning to use introspection to make marshalling from the one PHP integer type to the 8 different dbus integer types automatic, support for the missing data types, sending signals and receiving method calls, and addressing DBus object properties. The attached .tar.gz file contains a few examples that demonstrate the API in the examples directory. I've also attached those separately. regards, Derick -- HEAD before 5_3!: http://tinyurl.com/6d2esb http://derickrethans.nl | http://ezcomponents.org | http://xdebug.org
