Clustering - how can I.......

I have 3 Vaxen clustered (alright, 2 alphas and a PersonalAlpha, but I am still old fashioned enough to describe them as Vaxen). Their purpose in life is to run WASD. I want the higher-availability of a cluster, the ease of management of single UAF etc.....
So, the data source for the web server is an NFS file location stored on a Windows (sigh) server using RAID5. All is sweetness and light, single redundant data source and higher-availability web servers. Now, how can I get this connected to the internet and also get any inbound connection to hit somehting like a cluster-alias-IP address?
All this is running behind a small router which can only direct port 80 traffic to a single IP address. In the "good old days", I could have LAT running and use a cluster alias and a terminal would connect to whichever cluster node was available. But how can I do this with TCP/IP - or, can I do this with TCP/IP?
What I want is to have all port 80 hit any cluster node - and I don't have any load balancing servers to fiddle with TCP/IP after it passes through the router.
Any thoughts appreciated - even those that (may) say it can't be done without buying new and expensive comms equipment :(
