104A simple RPC mechanism.
105
106 A <i>protocol</i> is a Java interface.  All parameters and return types must
107 be one of:
108
109 <ul> <li>a primitive type, <code>boolean</code>, <code>byte</code>,
110 <code>char</code>, <code>short</code>, <code>int</code>, <code>long</code>,

119 All methods in the protocol should throw only IOException.  No field data of
120 the protocol instance is transmitted.
