In my educated opinion, prefixes that are not words by themselves are
never hyphenated (except possibly to avoid ambiguity).  This applies to
pre-, post-, non-, un-, in-, uni-, bi-, re- and so on, and there is no
grammatical reason why it shouldn't apply to multi- as well.  The rule
that once a word becomes common enough it can be closed up only applies to
compounds where each part is an independent word.  webster.com agrees with
this and also the dead tree dictionary I have here.  There's also a more
detailed explanation of this here: <http://www.bartleby.com/64/84.html>.
