Detailed Description

Trivial listener implementation that does nothing.

It can be useful, however, to force the local cache of remote objects to be kept up to date. This is because RemoteVobject only keeps the cache "fresh" so long as there some part of the application is registered as a listener -- if there are no listeners, then it tells the remote site to stop pushing updates.
