Close, try get_sync_info(). get_sync_info() get called when all the plugins 
get loaded:

e.g. osynctool --listplugins

Perfect example would be the SyncML plugin. It's registering 4 plugins in one 
get_version() call...


You do this with osync_plugin_env_register_plugin() or so ...


Just set different names for the plugins, then you can have several default-
configuration, due to the different plugins names.

Example:

------8<-----
osync_bool get_sync_info(OSyncPluginEnv *env, OSyncError **error)
{
        OSyncPlugin *plugin;

        plugin = osync_plugin_new(error);

        if (!plugin)
                goto error;

        osync_plugin_set_name(plugin, "syncml-http-server");
        osync_plugin_set_longname(plugin, "SyncML over HTTP Server");
        osync_plugin_set_description(plugin, "Plugin to synchronize with 
SyncML over HTTP");

        osync_plugin_set_initialize(plugin, syncml_http_server_init);
        osync_plugin_set_finalize(plugin, finalize);
        osync_plugin_set_discover(plugin, syncml_http_server_discover);

        if (!osync_plugin_env_register_plugin(env, plugin, error))
                goto error;

        osync_plugin_unref(plugin);

        plugin = osync_plugin_new(error);

        if (!plugin)
                goto error;

        osync_plugin_set_name(plugin, "syncml-http-client");
        osync_plugin_set_longname(plugin, "SyncML over HTTP Client");
        osync_plugin_set_description(plugin, "Plugin to synchronize with 
SyncML over HTTP");

        osync_plugin_set_initialize(plugin, syncml_http_client_init);
        osync_plugin_set_finalize(plugin, finalize);
        osync_plugin_set_discover(plugin, syncml_http_client_discover);

        if (!osync_plugin_env_register_plugin(env, plugin, error))
                goto error;

        osync_plugin_unref(plugin);

        return TRUE;

error:
        return FALSE;
}
----8<---

This is registering two plugins, which have two different dfeault-
configuration: syncml-http-client and syncml-http-server.

In the case of the SyncML plugin those plugins just differ in the plugin init 
function and discover function.

This is what i try suggested some weeks ago to  spawn several plugins for the 
mozilla-sync to avoid that user have to set the external_command by their own.

It's just about registering some OSyncPlugin* to OSyncPluginEnv ... even if 
those are the same shared-module or so.


Hope this helps.

Daniel
