Transmitting Haskell values

Hi all, sorry if it's a FAQ or I'm simply too dumb to look in the right places. What I want to do is to send Haskell values over a network to another Haskell process. Or save a Haskell value on disk and read it in in a later incarnation of the same pogram, or with a different program. Is there a good way to do this? Or, even better: a good way to find the right documentation for this sort of thing?
