multicore by(), like mclapply?

Package plyr has .parallel.

Searching datatable-help for "multicore", say on Nabble here,

http://r.789695.n4.nabble.com/datatable-help-f2315188.html

yields three relevant posts and examples.

Please check wiki do's and don'ts to make sure you didn't
fall into one of those traps, though (we don't know data or task so
just guessing) :

dear r experts---Is there a multicore equivalent of by(), just like
mclapply() is the multicore equivalent of lapply()?

if not, is there a fast way to convert a data.table into a list based
on a column that lapply and mclapply can consume?

advice appreciated...as always.

regards,
