Greetings!
Firstly I just want to say thanks for the hard work on this!
Any chance for a samba/CIFS module for this Rom? I'm using the 3.5 version (overclocked), but I'm willing to re-image with whatever version. No matter what I've tried I've not been able to get a working module to run on the R101.
I purchased an R101 reader from a Woot sale some time ago. I promptly used the latest that was available at the time for it, and sadly the performance was awful, wifi broke constantly, market and gapps couldn't work, etc. Needless to say the device sat unused for a good 6-7 months. I recently got curious again and found this thread, now I have a device that's actually very usable and functional!
I've actually been planning a project to use some sort of cheap Android tablet as a wall-mount controller for my home automation system. I've already developed a web interface for it (all home-grown linux based stuff), and the interface is designed to work well with both my Android phone as well as this R101 tablet. The idea is to take the setup of the tablet, purchase a few more, restore this setup to them, mount them on the wall, and enjoy.
One issue though is that part of what I'm designing involves some communication between the central home control computer and the rest of my devices. I generally use Samba shares for this, and have the back-end updating status files (ie, motion_sensor_kitchen.txt has an "on" or "off" in the file). I'm using Tasker to check for updates to these files, and if "off", then shut off the display of the tablet (with Tasker), and if "on", turn on the display.
So far the best I've been able to do is to auto-sync with an app from the market to a local directory on the tablet. This has been inelegant since the lowest sync rate I can do is 2 minutes. I'm shooting for it to turn on when the lights turn on (when motion is detected), so the key is to have real-time access to the files in question. This would require mounting the samba share directly to the R101.
I'm all ears if anyone has a suggestion on a better way to communicate to the tablets too.

My goal is to send some kind of notification to the tablet to turn the display on/off using from a remote computer...
Thanks for anyone who can assist.
