Frank, The way I would approach this for sharing data between two address spaces with IARVSERV is as follows :
(1) Before the IARVSERV is issued by the "source owning" program (in ASID #1) , the "target view" program (in ASID #2) must obtain the storage area that is going to be used to get the view of the data. (2) The "target view" program must then inform the "source owning" program of the view storage area STOKEN (or ALET) and starting address. (3) The "source owning" program populates the IARVRL fields with the information provided by the "target view" program and then specifies the IARVRL address on the RANGLIST keyword for the IARVSERV service. (4) Note that only the "source owning" program performs the IARVSERV service. Rob Scott Lead Developer Rocket Software 77 Fourth Avenue . Suite 100 . Waltham . MA 02451-1468 .

The method of creating the source data side of this process appears fairly straightforward, whether you choose to use private storage in the first address space or create a dataspace/hiperspace to use for sharing. The question is how to establish the 'connection' in the code running in the address space(s) that will use the target data. I'm assuming it to be another invocation of IARVSERV using the STOKEN and/or ALET from the original address space. Am I on the right track here or is there another approach ?
