I realize that it's a bit gauche to reply to one's own message, but I 
figured out the incredibly dumb mistake that I was making, and I wanted 
to record the answer for the archives.

The problem was that I was running LaunchAll from a shell that had a jar 
containing the classes that I wanted to be loaded across the network, so 
I expect that the problem was that the JVM running reggie was trying to 
load the application classes in a classloader that didn't know about the 
Jini classes.

Private message for Keith: You were wrong:  it wasn't codebase, it was 
classpath!  This is cold comfort for me pulling such a boneheaded move, 
however.
