Hi, thnx a lot for your answers, as for the devices I have no
attachment to a specific brand or something, at this point we are
doing the research first so, any known device with appropriate support
for this kind of application will be just fine, hopefully someone here
know about such device and will let me know. Secondly reading a bit on
the merapi forums I do came across an interesting project on this that
use an adaptation of JavaGPS to handle the data but It seems to work
only when a device is attached to a computer so I can't really follow
the actual position of a device remotely ( hopefully I'm wrong here
and someone will let me know ). Finally the Doug example of the
BlackBerry sounds great, I'm researching on this right now and I think
this could be my solution if I can't find a way to track the actual
position of a device remotely using just GPS.
Thanks again for your time and attention.

I have a small app running on my BlackBerry that posts my lat/lon to
my own webserver, which just stores it in a DB. The using whatever
serverside technology I want (java, php, etc) I could expose a web
service to return my coordinates. So you can either communicate
directly with the device via Merapi, or push data somehow from the
device to a webserver and then pull the data from the server into
your Flex app.

In addition to what Tim said.
The Merapi project (http://merapiproject.net/), is an excellent
candidate for a project like this. You can use Java to communicate
to the GPS unit's device drivers, and then use that data with
webservices or the yahoo maps API to serve maps in real time.
Just a thought.

If you want to do it in realtime you're going to first have to
decide what devices you support. There might be some standards for
communication, but others go off and do their own thing and those
might be the ones you want to support. Garmin often take a lot of
heat for this (despite what they're pushing with ANT+ standards).
Do you have a particular device in mind to start out, and have you
done any research on what dev tools they have available? Obviously
at some point you're going to want to abstract things out, but you
need to at least have a rough idea whether your design is even going
to work for real-world existing designs and products.

Subject: [flexcoders] GPS in Flex
Hi, I'm planning to build an AIR application but I have a major doubt
here, by looking at the amazing work of Doug McCune I think is
possible to integrate real time GPS data into a Map on a Flex
application, but my question is: how? Just in case the above is not a
completely clear explanation let me put it with other words:
I wanna know how ( considering first if this is even possible right
now ) to get data from a GPS device and load it, real time ( well,
pretty much real time ) inside a map on a Flex and/or AIR application.
I really hope someone with far more experience than myself can point
in the right direction on this one, thanx in advance for your
attention, and have all a great new year :)

Cheers,
Nate
