hi;

as the author of pyrt, i'd just like to say that extending it to act  
as a bgp speaker able to read an MRTD file in and push it out down a  
peering as a series of updates ought indeed to be straightforward.   
it used to be able to read routeviews and ris BGP update and rib  
dumps ca. 2001/2002 as i used them for testing before we got the live  
feeds from sprintlink setup; it's possible that new attributes and  
suchlike might mean that it has problems with current dumps, but that  
ought to be similarly easy to fix.  let me know if you run into any  
problems with pyrt and i'll see what i can do to help!

(i'm just pleased that someone might still want to use the code :)

Cheers,
