Alright very nice. This doesn't look too hard

Some follow up newb questions (I promise to try to read some beginner electronics sites in the meanwhile ):

* I see the board is pretty big, can I just cut it a bit to make it smaller?
* Just to be sure: I need to remove the current IR sender/receiver and plug in the right board whichever I would like to use (36 kHz for flash and other for phone)?

As for the BT option; I hoped it to be more 'standard' but I'd surely need to verify that.
