Nice work!  Have these modifications been accepted upstream?  It would
be great if your RFID reader was a standard part of GNU Radio -- I
suspect that a lot more experimenters would start messing with RFID.
And it would be even better if every interactive GNU Radio application
could benefit from the latency improvements you made.
