We do something close to that with migrated applications.  We have an
implementation of some MPE VPLUS Intrinsics on *nix platforms that is
written in C.  With an environment variable we can redirect the
communications layer to talk to anything else using xmlrpc-c.  

The way we use it is to run a handler on another box with a J2EE
applications server (in our case JBOSS). The code on the J2EE server
maintains state by creating a session that persists concurrently with the
life of the COBOL program.  After the COBOL program is launched, whenever
the COBOL program makes a VPLUS call the call is redirected through the
listener on the J2EE server to something else. In our case it is a session
EJB and ultimately either a JAVA Swing application or a web application. The
effect of all this is to treat any migrated COBOL program as a Web Service
by simply intercepting its VPLUS calls.  This also means that the COBOL
program is unmodified.  

What would be required to use it on an HP 3000 would be to port xmlrpc-c to
MPE/iX.  Since xmlrpc-c is pure C it would not be very difficult to do this.
We just haven't found anyone who is interested in getting it done.
