Hey all, thought you might be interested in a new wms/wfs client. I'm a big fan of it, and have mentioned it several times already, but they just reached 1.0 so thought I'd send the info along.
You can see a demo I threw together with GeoServer + Squid + OpenLayers at: http://geo.openplans.org/cholmes/ol-cache.html
In areas that someone else has already viewed it should be blazing fast, as it's automatically cached by squid. Since OpenLayers requests tiles from WMS directly, in the same way every time, simply standing squid in front of GeoServer turns it in to a tiling engine similar to Google Maps.
The other thing I love about OpenLayers is that it's great to use as a developer. After Google Maps hit a number of projects rushed to replicate the ajax feel. But that missed what was actually most exciting about google maps for me - that it became super easy for anyone to make their own map.
OpenLayers extends that ease, but takes it even more open, allows for even more innovation in mixing and mashing the map. It uses standard SLD, so a client could specify a different way to view the map. And I hope they get WFS-T support some time, so that users can edit the base map.
Anyways, I'll stop rambling, but it's a great piece of technology. Read on for details on where to get it.

OpenLayers is an BSD-licensed pure JavaScript API for building map
applications on the Web. OpenLayers offer offers the ability to
display a number of different types of data in a configurable mapping
interface.
On behalf of the OpenLayers development team, I have the honor and
pleasure of presenting version 1.0 of OpenLayers.
1.0 Release API URL: http://openlayers.org/api/1.0/OpenLayers.js
Latest Stable API URL: http://openlayers.org/api/OpenLayers.js
1.0 Release Tarball: http://openlayers.org/download/OpenLayers-1.0.tar.gz
You can see some example OpenLayers applications here:
http://openlayers.org/gallery/
The 1.0 release includes support for display of:
* Markers
* Popups
* Tiled WMS Images
* WFS Results (as points)
* Textual (tab-seperated) data
Development continues at a fast pace. Currently, the development
branch of OpenLayers supports:
* ka-Map data
* WorldWind data
* Untiled WMS Requests
* GeoRSS data
Our next release will support drawing and reprojection of vector data on
to:
* Google Maps
* Yahoo Maps
* Microsoft Virtual Earth
One of the many goals of OpenLayers is to allow users to use one API,
and one look and feel, but display data from any source. To that end, we
have created a system which allows for any data provider to create their
own layers to be displayed alongside any others in OpenLayers. The API
is inspired by the Google Maps API, designed to make the simple things
easy, and the difficult things possible.
Development of OpenLayers is currently funded in part by MetaCarta:
Please give OpenLayers a whirl and let us know what you think!
