I overcame this same problem by hacking a simple query mechanism into
bgpd. My netflow categoriser retains a small routing information cache,
and queries the bgpd for aspath/community information as and when it's 
needed.

All my netflow stuff is done off-host, and so is my netflow bgp. I use bgpd
with a view per router that I collect netflow data from, and my netflow system
is configured to relate these things together.
