Implement an ao2 output driver, derived from ao_oss.c, that opens both
/dev/dsps.

Great care will need to be taken to synchronise.  Best results are likely
to be achieved where the two card drivers have the same fragment
size.  OTOH, some delay in audio to the back is considered a good thing
(and is created in pl_surround) so perhaps the effect of poor front to
rear sync won't be so obvious.

I would like to see someone try it...
