Is there a mechanism to dynamically load a GWT Module?
The idea is to create a pluggable GWT-based system: a core GWT module that dynamically loads another GWT module and a bus communication system to permit the communication through loaded modules.
Any help?

To summarize, its possible, but not recommended. Your requirement is orthogonal to GWT’s philosophy and architecture. If you must, the GWT Exporter project is a useful starting point to enable communication between modules.
