Hello,
I’m trying to set up Infuse with Xubuntu. For the moment I’m strill trying to gather information on how it could be done, basically I need to find out how to share folder with the network.
If any of you have an idea on how it can be dona, help will be appreciated! 
NFS might be the best option for streaming in your case. Once sharing is enabled, your device will be automatically recognized in Infuse when adding a new share. More info here. Streaming From a Mac, PC, or NAS – Firecore
A guide which should help you get started with enabling NFS sharing can be found here.
