strictly speaking, if you are willing to write your own spi code, you could find tft displays very cheap on ali for example, and the overall cost of your project will be very low.
last week i received my 240 x 320 dpi spi tft thingie for under CAD 6. people are using those with esp8266, so it shouldn't be a problem with omega. i haven't tried it yet though, it's the last thing in a queue of a million things to do :)
Just a quick update - with the Omega2 this will all get much easier, as the Omega2 has a second serial port on the pins that were labelled GPIO 13 and 14 on the Omega1 (see new pinout). And these pins are available on the dock connector!
Also the software side will be probably simpler, because the second serial port will not be occupied by the system console.
if I am on my motorcycle and come home, I want the door to open automatically (if the radius is possible).
I see where you are going with this, a Bat Cave Garage Door. ;-) It certainly is possible. Anything that will try to automatically connect to your main controler via WiFi or blutooth (with proper security signature) will do to alert it.
About the open/close state of the door, maybe your system already has a light that you could use. If not, the simplest and cheapest way is to use a magnet switch (magnet on the door + glass fuse-like switch on the door frame).
FYI: I have produced some small updates to the Omega Arduino Expansion Board design.
Added a jumper to allow Arduino VIn to be connected to the External Power Sources and the Power Regulator
Allowed for usage of TSR12450 power regulator (see https://www.adafruit.com/products/1065) as a compatible alternative to the L7805 regulator
Essentially a Linux environment is required, but of more importance are the dependencies. These are mostly Python packages. We’ve tested Snoopy on Kali 1.x, and Ubuntu 12.04 LTS. We managed to get it working on Maemo (N900) too. We’re investigating getting it running on OpenWRT/ddWRT. Please let us know if you have success.
Are you using USB speakers directly into the Omega dock? I believe the error is because you need the speakers to be plugged into a USB sound card (since the Omega doesn't have a sound card built-in)
@Cody-Swann Thanks for sharing your project! We want to show you our appreciation by giving you an Omega2! Please email firstname.lastname@example.org with your shipping info or let us know if what we have on file from your previous order is ok!

The 16 PWM signals means that you can run up to 16 separate servos, but you would need an external 5V power supply with enough current to supply all of them. The Omega by itself can power 1 or 2 small servos under very light load, although it can get a standard size servo to turn a door lock here!
You would definitely need to find the maximum current draw of each servo (usually in their specs), and make sure your external power supply can provide more than the sum of all maximum currents (for safety).
Labelling each wire is very handy, you can either label by part/location or by #; the connectors on the Expansion are marked from S0 to S15.
