multi-threaded ifxclone?

I remember Madison saying at the IIUG conf last year that ifxclone is essentially an onbar process. I was wondering if it was possible to multi-thread it the same way we can with onbar. I tried setting BAR_MAX_BACKUP to 4, but it's still restoring 1 dbspace at a time. I can't find anything about this on here or in info center. If this isn't an option, maybe I should put in a feature request.

I found a session from last years IIUG conference by Hyun-Ju Vega and it says the following in the powerpoint: Source archive data is sent to target using SMX (parallelism is controlled by BAR_MAX_BACKUP ONCONFIG parameter on target) I set BAR_MAX_BACKUP to 4 on my target machine and it's cooking along with 4 dbspaces at once.
