Hi,
I use the ATT email->SMS gateway for all my alerts currently and have a goal to move to either some flavor (Prowl, Pushover, etc.) of push notifications OR using an Applescript method I've seen around the forums here to send my Indigo alerts via Apple Messages.
I've been leaning toward Messages, but the Push Notification services already have plug-ins developed by cool folks around here, which means it'll be easier on me.
My thinking on Messages over Push is I'd be using a native Apple service and not relying on (or paying for? can't recall if Prowl/Pushover have fees) a 3rd party application.
Besides a possible failure with the Prowl/Pushover service, it would seem there is possibly less latency by using Messages (though my theory there is merely an educated guess). It's also encrypted by default, has serious muscle/reliability behind the scenes, and the notifications are conveniently corralled with all my other txt/SMS/Messages in a single iOS (and Mac) app.
Where is the Messages plug-in?
Thanks for any feedback,
Mike
