I'd like to set up a webmap that clients can drop into their existing website. I'm thinking Geoserver, OpenLayers & GeoExt. It would be very simple slippy map kind of thing. Do I need Geoserver at all then? Just want to be able to use WMS/pan/zoom/turn layers on and off. If I ditch GeoServer, then do I need Apache?
Anyone who could point me in the right direction for a checklist or roadmap to offer up simple webmaps is greatly appreciated. I'm looking for info on setting up the web side of it, since I'm fairly good with GIS already.
