IMO, there are two classes of projects here.  The easy class are little 
samples or demos or examples which are (at most) a couple hundred lines of 
code.  These can live in the main llvm repo, f.e. under llvm/examples.

Projects that are bigger than this can be part of the llvm project 
umbrella if desired, but should live in a separate module.  For example, 
llvm-gcc, clang, stacker, java, poolalloc etc all exist this way.  The bar 
for creating a separate module is very low, so this isn't a big issue.

One real issue though is that these projects will get out of synch with 
mainline if noone is active to maintain it (e.g. java).  In my mind, this 
is actually a good thing: putting these into mainline would cause 
increased maintenance burden in the case when noone is interested in the 
project.  When someone later becomes reinterested in a project, it usually 
isn't too hard to synch the project up to mainline again.

Anyway, in short, bring on the deluge!
