R devel - Jul 2001 - marshalling/serializing of R objects for later execution?

I know that this was a topic in March at DSC, but I was suffering from
a nasty migraine that prevented me from paying as much attention as I
ought to.  What's the current state-of-the-art regarding
packaging/serialization of R objects?  Or is it still vaporish
(i.e. nothing built)? 

I'm a bit more interested in functions/closures than "ordinary
data".

best,
-tony
