I found an app that is apparently only for the iPad called the "Air Book Reader" but it is basically exactly what I want to use, just I want to do it for the Android. http://www.airbookreader.com/features.aspx
I tried calibre, but it doesn't offer an option to "stream" the ebooks; only to allow to download to the device. Same with moon Reader and the other popular ebook readers on the Google Play store.
I have a MASSIVE ebook collection of almost 100GB and there is no possible way to simply copy them to my Android device.
Also I will only be using it at home, so I only need to stream through my local network, from Windows computer to my Android tablet.
Note: I'm only talking about streaming ebooks to read. I already have apps to stream all my video files over the local network, and also I already have an app for audio files streaming.
