      Running code downloaded from the network raises several security
      issues.  Unlike the Java programming language, most existing
      reflective architectures have failed to address these issues.  There
      is a clear need for mechanisms to impose some discipline on the
      interactions between objects and meta-objects, so as to retain or
      improve the security mechanisms offered by programming languages.
      \par
      While the ability to dynamically associate objects with meta-objects
      is essential for developing flexible and adaptable reflective
      applications, reliability depends on mechanisms to regulate
      reconfigurations.
      \par
      In the design of Guaraná, a language-independent
      meta-object protocol, we have attempted to address these issues.
      This papers describes and justifies some of the decisions we have
      made in order to allow developers of reflective applications to
      balance flexibility and security.
