You can reference the algorithm without referencing the actual implementation
of that algorithm.  Read the license carefully...  It does not require that
software which uses it be identified in such a manner, but it is saying that
you can't call this _specific_ implementation the Joe Blow MD5 Function.

No, that is incorrect.  The particular clause that killed that one required
any software which included software (but did not necessarily mention features
or use of that particular implementation) with that license to mention the
`credit clause'.  There is a very big difference between the two.

So why didn't you actually get a legal opinion before flaming on this
list for no particularly good reason?
