I am thinking about adding an IR remote to a project I am working on, and I was curious on your thoughts about the easiest/best IR protocal to integrate using PBP. Philips RC5, Sony, other?

I have been messing with coding for some TV remotes I have in my house with pretty good results. Since I am thinking about getting a custom remote made I'd like to choose a protocal with the least overhead.

Thanks for any thoughts.
