It doesn't matter the direction. Once you have a connection either end can use it to send data to the other. You just have to create what you want the interaction to look like.

Do you want the client to send a command requesting data?
How do you want the data response to look like?

You can send variants, but it probably not worth the effort.

I've started using Network Streams for (very flexible) data communication between two machines.  I believe that there are Demo Projects that ship with LabVIEW (2012 and higher, for sure) that illustrate a Real-Time system (two machines, Host and Remote RT) each having a Queued Message Handler (with the Message Data being passed as a Variant) connected to the Message Stream so that the two machines can send Messages to each other.

If you look at the Sample Real Time projects, I think those are the ones with Network Streams.  The documentation is pretty good.  There are also LabVIEW Examples on Network Streams.
