No, there is no such think yet. It's on the roadmap. It's usually 
referred to as "subports".

That's a good idea. So far the discussion evolved around adding this 
functionality to standard TCP transport. Using a separate transport for 
"merged feeds" is probably a good idea as it clearly separates business 
feeds that are visible to the underlying network (tcp) from those that 
are merged with other feeds and thus not eligible for traffic 
monitoring, traffic shaping etc. (vtcp).
