[MC 1.2.5 | CC 1.33/1.4] Digital Rail Reader. Monitor those carts!

What is it?
The digital rail reader is a peripheral for computer craft. It consists of a single block that, when given a block update will check for a Minecart above it. It will then queue an event for the Computer it is bound to containing all sorts of juicy information.
How do I use this magic?
Simply place the Minecart reader next to a computer, then place a detector rail on top of the Minecart reader. When a cart goes over the rail it will trigger a block update, the reader will get information from the cart and queue it in an event.
Installation
You need CC 1.34 installed (along with Forge obviously).
1. Place the zip in your .minecraft/mods/
2. Run Minecraft
3. If you get an error along the lines of "Slot x is already occupied when adding…" then you have an ID conflict. In the .minecraft/config/DigitalRailReader/ folder there should be a main.cfg text file. Open it with notepad (or any other plain text editor) and change the block ID for "block" to something else (a number between 120ish-255). Run Minecraft again. Rinse and repeat until you find a block ID which is clear.
Crafting
O - Iron
R - Redstone
T - Redstone Torch

Parameters
Using os.pullEvent() you will get the following parameters back:

Note 1: The username param will only be returned if occupied is true.
Note 2: entityID is a unique ID given to each entity, use for tracking Minecarts.

Todo
1. Port to SMP (priority).
2. Carts seem to be double registering, I might have to implement some sort of debounce feature.
3. Investigate giving the contents of a chest cart and the fuel span of a funai cart.

Isn't CC currently 1.33? Anyway looks cool.

My bad :)/>/>.

Seems to be working with 1.4. Except my consoles have all frozen up (seems to be a Windows thing, happened to both my installs simultaneously when I set quantum run on one of them to capslock before using a computer. Weird as hell) so I haven't been able to test it really (but no errors?).

Does anyone know how to change the title of a thread?
UPDATE: Works fine! (Yay!). Above question still needs answering :)/>/>.

Go and edit your first post then click on Use full editor.

I just edited it to read 1.33+ for you :)/>/>

Thanks Cloudy!
Just edited it to read 1.33/1.4 (it seems to work fine on both, thanks for the tip xuma).
It seems carts get registered twice, I'll fix that ASAP (I just need to check if I'm registering the event twice, or having my event trigger twice). Working on SMP now… Hopefully.

Me thinks I have a working SMP build.

Does it support carts from other mods, e.g. Railcraft or the Trains Mod, as they will also trigger a block update?

Can you do an example of program?

This is because you get a block update both when the redstone activates and deactivates.

My apologies. I'm pretty sure it checks for a redstone signal so the deactivating rail wouldn't trigger it, but I'll check anyway.

Update please?

It will be on MiscPeripherals, but will be improved and won't work the same way.
