API display text triggered by external event?

[MarkHarrison]

Is there an API call that will allow me to display some text (on an MVP) when something external happens. IRRESPECTIVE of which screen is showing.

The plugin I want to develop is a "phone call from...." popup message that overlays the screen.

The "backend" is easy - I can write some .NET code to trap an incoming xAP message, and parse that to work out whether it's a phone call. Then, if it is, I can display a message on screen... or can I?

For those not familiar, xAP is an open protocol for Home Automation (http://www.xapautomation.org). As such, there are already drivers for various systems that send a xAP message round the network when the phone rings. I want to be able to trap these messages a popup on my telly, using MVP, when this happens.

I think Sub is going to add an OSD api. Though not sure if this is purely when watching video/live tv/etc. of if this can apply to any screen you may be on. I assume you are looking for something like a broadcast message api?

A caller id plugin would be great.  But like Colin said, it would require the capability to be added by sub.  My MSN Messenger plugin that I'm currently developing could use this as well.

Seems limited, from what I see, as to what modems are supported to generate the xAP Schema for CallerID messages. Is there something other than xap tel to do this?
