This question has relevance to the ASPA method for route leak
detection.
Is it possible that an ISP AS A peers with a customer AS C via a
non-transparent IXP AS B?
IOW, the AS path in routes propagated by the ISP A for customer C's
prefixes
Right - but IMO route leaking can happen both in the Internet or in
customer <- via IXP -> content provider interconnects.
And in the latter case - especially for those with open peering policy -
often going via RS. After all this is how route servers are mainly used
today :) So both sides will

Well I think the answer is - it depends.
First IXP fabric can be used as pure L3 share LAN or can be used (and it is
often the case) as a p2p emulated VLAN over such L3 shared LAN.
Now if this is L3 shared LAN still customer and ISP may peer directly and
no third party traffic would be accepted

This question has relevance to the ASPA method for route leak detection.
Is it possible that an ISP AS A peers with a customer AS C via a
non-transparent IXP AS B?
IOW, the AS path in routes propagated by the ISP A for customer C's prefixes
looks like this: A B C.
I.e., can the AS of a
