Re: Plugin integration

[Christian Grothoff]

The DHT will find your plugin automatically if it is installed in the 
right directory and has a suitable file name following the naming 
conventions. Your plugin must expose the right symbols with the correct 
API, and then the DHT will basically 'ask' your plugin what block types 
it is responsible for, and for those then ask your plugin to evaluate 
queries and replies.

Depending on what your blocks look like, you may be able to re-use the 
logic from the FS block plugin, or write new logic, hard to say, depends 
on what you are storing ;-).

DHTU works a bit differently, in that here you need to explicitly 
configure the plugin (the underlay plugins are not automatically 
'discovered' and used). DHTU is really just there to allow a DHT node to 
communicate with *neighbours*, it doesn't make routing decisions. Thus I 
don't think it is suitable to 'guide' each message, but maybe you mean 
something else by 'guide'. DHTU is for *transmitting* messages.
