Without 3rd party hardware or software, the only way to do this is to use Bluetooth messages. For example, you could write motor power to a Bluetooth mailbox on one NXT. The other NXT just has a simple program with a loop that reads the Bluetooth mailbox and connects it to a motor block.

This is more of a LabView answer than a Mindstorms answer, but you should be able to create a SubVI that represents a task, and then you can place that in the main VI. This help document might be useful: http://zone.ni.com/reference/en-XX/help/372962A-01/lvnxt/creatingusingsubvi/

I don't know of any comprehensive parts dimension reference, but following should help you get started. You can calculate part dimensions using fundamental dimensions of LEGO parts. The distance between holes in technic bricks is 8 mm (8 mm is one of core dimensions in whole LEGO). So for example, lets take a beam (aka liftarm) with 7 holes, then length is ...

It is possible to connect a Playstation controller (Sixaxis or DS3) directly to the EV3 brick over Bluetooth. Here is how I do it: http://www.pabr.org/bricks/brickhid/brickhid.en.html There is a servo emulation mode which should support rack-and-pinion steering. Note that this is a quick-and-dirty proof of concept with several limitations: A PC is needed ...

Raw sensor value works, but shows a level of dark, not of light :), meaning that higher values indicate lower light. Ambient light works directly, but for reflected light you need to insert a EV3 Color Sensor block with Reflected Light mode to turn on the light in the NXT Sensor. After that, use raw values or the Sound sensor block. The Sound sensor block ...

As mentioned by @guestguy123 and @eficker, it is easy to combine an EV3 cable and a PF cable to make a custom cable that allows the EV3 to control. This can even be done without soldering - I just twist the wires together and tape them with electrical tape. The full schematic is here: All you need is 2 resistors (1x1kOhm and 1x10kOhm) which are cheap to ...

There is always the .NET API for Windows 8/ if you don't mind programming an app yourself (this would work for Windows/Windows Phone 8). The sample provided would allow you to control the individual ports of the brick but it doesn't take much to change this to control multiple ports from one button press. https://legoev3.codeplex.com/ Sadly this solution is ...
