And, here's a mailing list:
http://lists.eogeo.org/mailman/listinfo/tiling
Now that GeoRSS (http://www.georss.org) is more or less ready (we
still need to do a few final text tweaks and clean up the web site) a
tiling scheme seems like a great Next Thing.
It seems that we need to define what the resolution levels are, work
out a tiling scheme so that clients can request tiles either by bbox
or by name (maybe these are the same thing) and so that tiles can be
cached and distributed.
If we then define a dozen or so canonical layers with specific names,
we can tile each of those layers into the tiling scheme and people
could just assume that those layers will always be there. Things like
"boundaries", "water bodies", "roads", "cities", etc.
If the tiling scheme uses WMS requests, then the tiles can be
generated from some carefully crafted WMS engines with carefully
maintained data sources. People could cache tiles using Squid,
modified httpd software, or perl, python, or ruby hacks.
The tile fetches would be against web servers that are essentially
serving static files and thus ought to be blazingly fast.
The whole thing can then be wrapped up in a nice bundle as a WMS
profile.
And, drum roll.... GeoRSS can be used to describe the tiles and could
be used to help track who has tiles. (Thanks to Andy Hook for that
inspiration)

Now that the chatter has died down, it looks like we have three

udig or codehaus and worldwind
I'm not personally concerned with udig or worldwind association I
think if we put useful stuff out there, people will use it and will
hopefully contribute.
Here is a space - login to create an account (and thus be able to
edit). If you use it cool, if not
it is open for others.

Thanks for putting this information together in a public location -
something we will all enjoy.
