Hi,
sorry to chip into the discussion so awfully late. Anyway, to answer the
bandwidth question I created the following report for the ros wiki mirror. 
http://ros.informatik.uni-freiburg.de/analog/

Here is the summary:
  Average data downloaded: 88.75 MB/Day  (=621MB/Week)
  Tarball download (as stated by Brian): 11GB/Week

Greetings,
Felix
