JFusion started as a vbulletin specific bridge vb_auth, because of my frustrations with the lack of Joomla 1.5 bridges. However I soon realised that many people where coding similar bridges for different software's and each programmer was somewhat reinventing the wheel. JFusion was then born with the idea of making Joomla 1.5 bridges much easier, where a plugin contains only the specific software codes (SQL statements to fetch user information, etc) and JFusion would do the rest of the work.
Collaborations with different software commities is extremely important to me. JFusion is an open-source free software and many people have contributed to the code making JFusion a better product for everyone. With regards to SMF, I am working with Toby from J2SMF on creating a version of J2SMF that works with JFusion and will allow many different software's to take advantage of his brilliant piece of coding. I would be more than happy to work with ilwoody on a Joomla<-->SMF bridge, if he is interested. As we all have the same goals in the end.
JFusion has been completely rewritten in the last couple of weeks. Multiple simultaneous integrations are now possible (ie. have Joomla and SMF and magento ecommerce user integration). AJAX usersync in the Joomla administrator for large sites to prevent time-outs. Code has been optimised for minimal usage of resources (minimal SQL queries, recycling of JFusion objects with a new php factory, single quotes vs double quotes, Model-View-Controller (MVC) code structure, etc etc). I am hoping to release a JFusion 1.0.7 alpha, with Joomla<-->phpBB3 only support at the end of this weekend. This will allow feedback on the new framework and allow other developers to work on JFusion plugins. I will then focus on getting the SMF JFusion plugin upgraded with the new functionalities, work on the J2SMF type visual integration and get a discuss-bot up and running.
You can have a look at the new framework and code on:www.jfusion.org/api [nofollow]
Still a lot of work left to do, but I am excited that these new functions are within reach now.
