Hi Peter,
I'd advice you to read Internet Routing Architecture by Sam Halabi. I
believe it to be the BGP Bible. If you read it, you'll find it says where
next hop processing is concerned, bgp confederation (while peering between 2
private AS's) would follow the principle of iBGP and NOT modify the next hop
values. Its only modified in "true" eBGP peerings.
If any of the (BGP?)Gods here think I have mistaken the behaviour, please do
correct me and provide the right explanation :)
