The impetus for this email is actually the pain I'm going through to get 
it to Martin.  Putting it all on a geotorrent is easier for me, though 
harder for him.   So I'm working on ftping it, and should hopefully get 
it all across that way and he'll combine and whatnot.  I'm happy for his 
stuff to be 'the' osgeo package, but I'll probably still want to 
distribute mine, both as a US focused one and an example of how to set 
up GeoServer.

I have a 'geoserver data directory' that links to the TIGER/VMAP0/GNIS 
metadata.  Tiger in particular is not all that helpful, since it says 
nothing about particular layers.  So I include a bit more in the W*S 
'abstract' section of each layer, about what it contains and what 
generalization we did, ect.

I can create a ticket, but I'm not sure what for?  Just to have someone 
make a place for me to upload this to?

That'd be great.  I'm happy to share the load on TOPP servers, I've got 
2-3 boxes I can put it on.  And I may know a few others who might offer 
resources as long as we're sharing.  I just don't want to be hit with 
the whole load, and I hope that this way as it gets out there more peers 
will share the load as well.

Cool, I'll check this out.  I had good talks with Creative Commons, 
which lead me to my interpretation of by-sa with regards to geodata, and 
why I chose it.  Like it doesn't 'infect' other layers.  I need to push 
on them more to see where they're at and to push on it more.

Yeah, I'll get some advice from CC and SFLC before I go live with it, 
hopefully set something up early.

Thanks!  Yeah, have been going sort of on my own, but I want to put it 
in line with OSGeo, and to do more for OSgeo as I've been a bit 
negligent lately.  And geodata is by far the area that excites me the most.

Oh yeah, I've also got 2004 .6 meter orthos for all of NYC.  About 5 
gigs of tiffs.  I can throw them up on a geotorrent as well.  And don't 
we also have the boston orthos?

Next step for me after that is to set up a WMS and TileCache.
