Yes I think it is quite possible.

Yes, I could use some.  Read below about the test_generators
failure below.

I have just committed a fix for test_uuid.  It is an issue with creating
a hash for a uuid.  My test results are for a 32-bit machine.  I believe
my fix will now also work for 64-bit machines.

The failure for test_generators is with the name_generator and wide
strings.  I have learned that most platforms / compilers have
sizeof(wchar_t) != 2 and I wrote me test for sizeof(wchar_t) == 2.  I
believe the results are correct, but my tests don't show that.  I push
the bytes of the string through a sha1 function and need the hash to be
the same for the same string regardless of the size of wchar_t (I
believe).  I may just remove the wide character support (and place a
example in the docs of how it could be done) until a better solution is
found.  Does anyone have another solution?
