There is a run through on the Oracle web site of how to setup a cheap 
RAC (Real Application Cluster) using a few linux boxes and an external 
firewire enclosure.  This actually does allow for simultaneous access, 
although in the run through they are using OCFS (Oracle Cluster File 
System) to do that.  Not all firewire enclosures can do it though.  
Haven't actually tried it yet but it looks pretty straightforward.  I 
don't think there is anything about the multi-system access that is 
Oracle specific.
