It avoids complex patenting issues by using proprietary Adobe Flash. From the other side it
may grow into independent solution because it uses OpenLaszlo RIA framework rather than a
particular proprietary vendor language, and after framework evolves can use other frontend
representations such as javascript.

itself uses Apache Axis2 for the SOAP / REST API. !OpenMeetings was reworked to use Apache
OpenJPA instead of Hibernate. Since revision 4000 (version 1.8) all dependencies to Hibernate
have been removed from the source.

Doing that we will improve our release processes, quality standards and it should give a planning
reliability to our end users. But our main motivation is that our project is about collaboration,
communication and enabling people to easily interact with each other. We think that the "Apache
Way" of community driven software development with flat hierarchy and transparency in decision
and design will reflect best those core activities of our software.
> Well, or course we want our project to be alive, and useful. Several contributors have
former experience with Apache Harmony project (which previously has been known as SourceForge
ORP project). Apache brand is really helpful compared to SourceForge brand for community building
and getting support from commercial companies. From the other side org.apache.harmony story
shows that the brand cannot help when there no community remain. Hence we try to keep people
interested, and the product developed at the first place, thus supporting Apache brand fame
with good facts.

> Adobe Flash (by means of !OpenLaszlo) and open source projects compliant with current
Apache policy. The UI code is compiled by using !OpenLaszlo, not by using Adobe products.
!OpenLaszlo is licenced under the CPL. !OpenLaszlo's concept is that you write the code in
a XML based approach, it is possible to compile the output to Flash or DHTML/HTML5. So on
the long run it might be possible to replace the Flash UI with a DHTML one. But as there is
little multimedia support in HTML5 especially for Webcam and Microphone access it is not possible
yet to prevent using Flash in general. The needed Real-Time Communication could be done using
Ajax and HTTP-Push mechanisms like Comet instead of AMF which is currently used.
