Roger, One of the Applications we are deploying (AND it is a BIG ONE - 380 SERVERS) is the Fed's PACER court system with Electronic Filings.
We have renamed it to MEC (Mississippi Electronic Court). It eventually will have a total of 380 servers, 180 On the LPAR's z/VM and the rest on VMWARE. Cannot be helped on the VMWARE since the FEDS have a proprietary PERL library and some encryption routines the will not release source to them and they are x86 based. The Database backend is Informix on zLinux with replication all on SuSe 11.1, multipath to a 8300. The Attorneys in the STATE love the system since it looks just like the Feds System, but we are doing certain enhancements to it. Maybe here is a system for you? Just Sayin' ..
