Is there a way to preview RAW photos on an Android tablet from a PC over a network? Is there a way to share RAW (Canon) photos over a network and preview them on an android tablet (Kindle Fire)?

I want to be able to quickly preview new photos without having to convert them to JPEG and copy to the tablet.

One potential possibility I can think of is exposing the photos as an RSS feed and using an android app like Just Pictures to consume the feed, but I don't know of a way to create the feed in Adobe Bridge or Lightroom.
There are Apps which allows you to connect to your PC and control it with your Android device. These are generally referred as Remote Desktop Applications.

For Android, there are many remote desktop apps, one that I have tried is called Splashtop. I know LogMeIn, which is quite famous among remote desktop softwares, also has Android/iOS version available.

However these Apps are usually not free.

While these Apps can do exactly what you want, it can also do much more than just viewing RAW photos, basically it enables you to use your Android device as your PC's LCD monitor, so you can run any programs, open any files etc. Therefore these Apps tend not to be cheap.
