correção de bugs

Um bloco do if (menu instanceof UnicastSubMenu) estava duplicado e
incompleto (sobrava um fragmento com reticências soltas), o que
impedia a compilação do núcleo. Remove a duplicação, mantendo só
o bloco correto e completo que já existia logo depois.

 - A ferramenta pitiupi (P2P)

+### Plugins: 
 - Um plugin de Chat
+- Um plugin de Chat multiprotocolo (TCP/UDP)
 - Um plugin de ScreenCast
 
 Cada um destes projetos deve ser compilado individualmente. Para isso, use a ferramenta ant no diretório do projeto.
@@ -21,9 +24,26 @@ Para criar links simbólicos no Linux, use o comando:
 ```
 cd pitiupi/plugins
 ln -s ../../pitiupi.chat/dist/*.jar .
+ln -s ../../pitiupi.mpChat/dist/*.jar .
 ln -s ../../pitiupi.screenCast/dist/*.jar .
 ``` 
 Isso deve resolver!
 
-Para criar um novo plugin:
+## Como um plugin conversa com o pitiupi
 
+Um plugin nunca recebe acesso direto às classes internas do núcleo (ConnectionManager, GuiManager). Em vez disso, recebe uma facade, a classe Pitiupi, que expõe só o que um plugin precisa: enviar mensagem (multicast, unicast ou tcp), abrir conexão tcp privada, ler nome de usuário e porta, criar menu.
+
+```java
+public abstract void createPlugin(Pitiupi pitiupi);
+```
+
+## Para criar um novo plugin
+
+1. Implemente `pitiupi.models.Plugin`, incluindo `createPlugin(Pitiupi pitiupi)`
+2. Registre a classe em `src/META-INF/services/pitiupi.models.Plugin`, com o nome completo da classe numa linha
+3. Compile com `ant jar`
+4. Linke o `.jar` em `pitiupi/plugins`
+
+Use `pitiupi.chat` como referência — é o exemplo mais simples e completo.
+
+Plugins que ainda não foram atualizados para a Pitiupi (como uma versão mais antiga do screenCast) não compilam contra o núcleo atual e precisam de migração antes de serem usados.
