Yes, I am, but it does not do file sharing, just printing.

What I did was set up a logical IP on both machines and if the  
fallback node detected that the other node's primary IP went down, it  
would turn on that interface and start samba. Not exactly the most  
perfect setup but it seems to work pretty well. I use regularly  
scheduled rsyncs to keep the various tdbs and printer drivers in sync.

For file serving you'd probably want to add a stonith device and then  
have both machines attached to a scsi array.  There's still that  
array being the single point of failure, but it's better than nothing.
