OK, here is my table `pong`

mysql> select * from pong order by id desc limit 25;

Every hour each `node` updates the table with the different values, gateway, metric...

I want to query the table for each node's time since last update so I do this:

mysql> select MAX(id) as maxid,node,SEC_TO_TIME(UNIX_TIMESTAMP()-UNIX_TIMESTAMP(MAX(datetime))) from pong group by node;
+-------+--------------+-------------------------------------------------------------+

That works fine, now I also want to get each nodes most recent gateway, metric, version, and fb along with the amount of time since last update.  So basically I want the query above including the results of:

select metric, gateway, version, fb from pong where id = $QUERYABOVE.maxid

all in one query, any ideas?
