Shmuel, The different NetID problem can be expressed in these terms: With subarea SNA, between subarea nodes, you can have network boundaries only INSIDE an NCP. This clearly excludes VTAM to VTAM SNI over a channel. With LEN and APPN the network boundary can be on the link between nodes. If the network boundary is between APPN Network Nodes, at least one of them needs the additional smarts of an APPN "border" node - and if only one of the Network Nodes is a "border" node, the other is the entrance to a peripheral network - I think I've expressed that correctly.
With subarea peripheral nodes there's a further subtlety in that the SSCP-dependent logical units (LUs) can participate in sessions in the subarea network using a NetID different from that of the SSCP which has activated them. I only know this because I once claimed in a "forum" such as this newsgroup that this wasn't possible and got slammed down by a VTAM developer!
