I am not entirely sure what you mean. There will be dynamic assembly in the 
next beta but it is of a different kind than what you are talking about. It 
is described at 

http://nagoya.apache.org/bugzilla/show_bug.cgi?id=12402

However this does not seem to be what you are after. It seems you want to be 
able to host another container (effectively a Connector container). Is this 
right?

Do any top level blocks depend upon these Connectors? If so then you are 
probably going to have to implement them in a way similar to how 
SocketManager operates. ie Have a ConnectorManager and have the other blocks 
depend on it and have those blocks use ConnectorManager to lookup the 
Connectors.

If no block depends on a Connector (but some Connectors may depend on blocks) 
then it may be best to implement this as a "sub-container". At the moement 
this is not well supported. It is on the agenda for implementation after the 
next release but that could be a while off.
