Yesterday, I presented and demonstrated SCA for PHP at the Zend/PHP Conference and Expo 2006. You can download the slides here. The session was well attended and I got some good questions at the end. A few people came up asking for the samples I demonstrated (showed how one line of code could be modified to switch from providing a soap/http service to a json-rpc service - I think it's cool, but then I would :-D ).
We are in the process of moving the SCA code into PECL. It will appear in the recently renamed SDO project, which is now called SCA_SDO. I'll put the samples in as part of the move into PECL and blog once this is completed.
I'll blog more about the Zend Conference when I get back...
