The Search for Ho

Suppose we now have determined and calibrated the Cepheid Period-Luminosity relation and have used it to find distances to some nearby galaxies. How can we proceed from there?
The Tully-Fisher Physics or Black Magic?
Current Limitations in the determination of Ho:

(m-M) LMC: (18.35 -- 18.50). Cepheid vs. RR Lyrae zeropoint discrepancy; SN 1987 Ring
M100 and depth of the Virgo Cluster
Rotation Curves and their details --> fundamental limits in TF relation
SN Ia What is their Luminosity Function?
