Can't you accomplish the same thing by (ugh) creating TSAF virtual machines in the 1st and 2nd level systems and connecting them via VCTCA?

By attaching one local end of the CTC to the virtual machine hosting the second-level VM (in System-B), I basically created a linear network like this: Node B ------- Node A---------Node X (1st level) (1st level) (2nd level) Node X accessed my 1st level SFS (in Node B) via Node A, with no problems whatsoever. It felt a bit funny sending data on a two-way round trip to Node A, just to get it into the 2nd-level VM, but it was still as fast as ever. :-) Note that the ACTIVATE ISLINK commands were done in nodes X and A, nothing at all was done in B. If you already have such a CTC, the whole setup is about a minute! (One ATTACH to give a CTC address to the 2nd level host machine, and two ACTIVATE commands).
