"We also had problems where transit customers said don't want to be
exported to a certain IX point of presence while he wanted to be
exported at a different location."

That's a fairly normal request. I think nearly every major IP transit
provider has built out a BGP action community system to allow their
customers to control prefix announcements in the way you're describing
it here (e.g. prepending and no-export to certain peers/upstreams). Of
course outbound traffic from your customer to "the rest of the world"
can not be controlled that way.

Best regards,
Martijn
