Ditto Paul's points.
Folks should be requried to post minimal metadata in order to register their
data.
I assume the model is the directory is centrally located but the actual data
is dispersed to various download points on the internet. Some QOS minimum
should be required to stay registered and those who fail to provide a useful
download point should have their ercords renmoved or flagged as less than
useful.
Hard to say were the revenue would come from for the host. Perhaps charging
folks to register any significant amount of data would be one source.
Providing an ftp site for rent to store the data another. I would suppose
lots of small providers would not have a good way to have a public internet
ftp site.
Something that may be a nice feature to sell is a way for an organization to
provide a view of the stored files that is limited to their data. Not to
exclude others but to provide a well organized public face to their data.
This may allow small jurisdictions (Cites/Counties/etc.) a cheap way to get
a public GIS download presence. Something akin to the google.com search
limited to one newsgroup.
BTW I think this model was proposed by Dimitri Rtow of Manifold.net a long
time ago as a solution for distibution of public domian data.
