... There's a minor taste issue that I want to bring up before its too late. The current interface suggests (but not enforces) that Service("someid",NULL) asks whether this protocol is supported or not, and doesn't cause any action. If a plugin just wants to signal something and has no additional data, enforcing this rule would require some dummy pointer to be sent. However, the plugin could just take action even with Data=NULL, violating the rules.
Variants for this:
- Keep it as-is
- Drop the supported check from docs - each plugin can offer a check if
it likes 3. Introduce a constant handle, so Service("someid",QUERY_SERVICE) is the supported check
4. Service("?someid"), maybe...
(Not "someid?", which would be the "natural" way to form a question, since "?someid" makes it simple to check for the '?').
