1. The DS2408 seems like a better choice -- ot has 8 bites and a special mode (that isn;t currently implemented in OWFS) to do serial handshaking.
2. The 1-wire but is serial -- 1 bit at a time. OWFS doesn everything in bytes, except the search algorithm, but that jut means bit-banging 8 bites, or doing higher level read/writes if the adapter supports it. The adapter will do bit-level communication. 3. There is no "slave" to "slave" communication, so it's better to keep the data on the master. So the real question is what data rate does your IR expect? At regular speed, and with special modes, you can output 16k bits/sec = 2k Bytes/ sec. (Less any communication overhead).
