If you want to do this on the client side: Tim Schaub has developed basic buffering in a sandbox. Currently, there seems to be some interest in this again. See [1]. Another option that Tim Coulter and I have implemented successfully in a project is using a WFS (e.g. GeoServer) and query the features inside the buffer on the server side. This is as easy as issuing a request with a DWITHIN filter, which OpenLayers does support. Regards, Andreas.
