Currently the only way I know to share your PlayOn media with friends and Family is if they are on your home network and run the the playon app w/ their device (phone/tablet for example). This is very limited in my opinion, especially when you have other products that allow this feature.
It would be improve the product if it supported remote sharing features like this (or something similar)

Please let me know if there are specific questions or use cases for this features.
Thanks
