We should be able to drop a jar into the distribution and drop a module file to make the distro pick up plugins.

There are a couple possible issues: The classpath of distribution is static inside the manifest. So we might have to make that easier to update or add a plugins/ folder for dropping plugins.

Then on plugin end, we need to think about making the drop easier ... what the plugin needs to drop is: all its jars, all jars that are not already present in HC distro + the module file. It is certainly possible, but would be nice to provide lite/dropin packaging for that.
