We're starting work on doing history in WFS.  See: 
http://docs.codehaus.org/display/GEOS/Versioning+WFS

Have done a review on how others do versioning, and have an 
implementation proposal sketched out (which I've yet to review).  Would 
love to make postcode editing a target for this.

Also I'm dumping our tiger database on http://sigma.openplans.org to 
telascience as well.  Want to eventually make it a download from there, 
though perhaps we should consider torrents or something for large 
downloads?  This is probably about 4 gigs of data.  I can put your 
postcode data up on a GeoServer there, and we can use openlayers and do 
some pre-caching with their TileCache stuff.

I'm actually partial to Creative Commons licenses.  Shoot, I never did 
my report on the Science Commons conference.  Basically they believe 
that CC licenses can be used for data.  I'd prefer that route because 
the option to release things with attribution.  And some may want to go 
with 'non-commercial'.  Basically it allows more options.

They were going to write up a FAQ, and we could get some specific 
mapping questions in there, and hopefully point people at that.

best regards,

Chris
