I agree with Steven´s I'd rather avoid HMAC-MD5, just as a matter
of future-proofing. And more.
In am nearly sure that a preimage attack (MD5) will be found in the
next two or three years.

A couple of (rather uninformed) thoughts regarding HMAC-MD5: First,
how could collision attacks be extended to preimage attacks? And second,
how would preimage attacks affect HMAC-MD5?
For a preimage attack, consider the simplest case, a single input
block of 64 bytes. Then Hash = IV +
