Lib and I had a go at providing this for the community as requested.
You'll see from this link (http://www.minecraftforum.net/topic/1543523-dynmap-dynamic-web-based-maps-for-minecraft/) that, currently, the only support for MC1.5.1 is the 'Forge' flavoured variety. The bad news is that Forge requires a server *and* client install which we agreed makes it a non-starter.
So until Bukkit is up to speed we need to postpone this for now.
Thanks to both of your time and efforts guys!!! We shall wait with baited breath
