What is a accurate way to generate and decode IR signals?

Question

I want to receive and generate IR signals with my PI. What is the best way to reliably do this? Would it be with something like this?

You should look at LIRC. I bought a cheap IR sensor (Philips OVU412000) from ebay and set up LIRC to receive signals from a TV remote in order to control a program I wrote. Works great on my Pi. I haven't looked into generating signals, but I think LIRC is capable of this.

Here's a project on how to use LIRC to interface the PI to a home made receiver and transmitter. There is also a third schematic for a transceiver.

The receiver looks to be pretty simple, just a TSOP1238 directly connected to GPIO pins 1, 6 & 12 on the Pi.
