For the BBN code I believe the main changes were: first change all the 
hier_block to hier_block2, then you have dig a little bit into the 
internal flow graph code and figure out what the inputs and outputs are, 
as you need to set the io signature 
(http://gnuradio.org/trac/wiki/Tutorials/WritePythonApplications helps - 
about half way down you can find the instructions on creating a 
hierarchical block).  The flowgraph code then gets connected a bit 
differently, as you connect from self (input) to the internal blocks 
back to self (output).  Unfortunately I've been pretty bad about keeping 
track of my changes, so I need to reorganize a bit before I could just 
send you a nice patch to apply, but the main changes are in 
bbn_80211b.py, bbn_80211b_pkt.py, and either bbn_80211b_rx.py or 
bbn_80211b_tap.py (depending on how you want to look at the traffic - or 
both). In other words it's the code in the gr-bbn/src/examples directory 
- nothing in the src/bbn directory needs changing.
