Subject Re: MINA and prebinding of privileged ports
Date Mon, 25 Feb 2008 04:21:19 GMT
Hi David,

Unfortunately, we decided not to add any new features to 1.x.  Any new
features will go to the follwing milestones of 2.0.0.

IIUC, your request is that MINA should provide a hook so you can do
something before listening to the channel, right?  It shouldn't be that
difficult to add such a hook because we already have an
IoServiceListener interface.  We could add another handler method there.
Does it sound good?  If you have some time, you could file a JIRA issue
regarding your request so we can keep track on it.
