Sorry, I didn't realize MultiplexingMediaserver was in use somewhere 
because it didn't work. Now I see we could because the problem was only 
with pointers.

Here we could copy the old MultiplexingMediaserver for now.

We have had the CVS version too long in unusable state - for everyone 
except our research group. It is a hack but doing it the right way takes 
some time and can easily be done later.

At the moment I see it being used in TestImpl, Client and NileDocument. 
For the Client it works to the extent I've tested it. For TestImpl the 
hack works. How should it work in NileDocument?

When we are to do multiplexing the right way, we should have it specified 
first.
