Short answer: doable, but not easy. Slightly longer answer: there is simply too much data, the bandwidth too small, and the windows too small to not have some sort of detailed plan. One example plan: the last step in the batch process is to simply FTP the updated files to the remote site. MVS to MVS compressed FTP's are pretty efficient (TYPE E, MODE C). Onlines are much more complicated as you need a Point of Consistency (POC). Flash copy and XPPRC could be tools. Or ADRDSU to disk, then FTP that.
That would be overkill. FlashCopy copies, DSS copies are just too big, even after compression. Do you suggest to copy whole volume, or database to remote site ? It is too big amount of data (of course it depends on the shop), it is definitely batch process (non-continuous), so I'd vote for PTAM in this case. Regarding to original thread: yes, it is possible to transmit non-sunchronous remote copy traffic over IP. Bandwith should be greater than average update activity.
