'[PIC] PDA Ir interface'

So a client calls up....
 
 "we want to use a PDA to get data from our box, using infrared to do it....."
 
 OK, so I'm thinking first.....use the UART and tie a IR detector/decoder to it...errr...wait...I know they have IR transievers but is there such a thing as a IR serial interface?  I thought someone on here said they used IR instead of a 9pin D and such for serial debug.  So if that exists...halfway there.
 
 The other side is the PDA.  Again, back of my mind says theres been a discussion on this.  Not looking at used PDA's per say but whatever is currently out there..standard models.  Is there a model that allows user app's to be written for it? Are they running windows CE or windows mobile and can do this easily?

Pretty standard stuff. Well defined protocol stacks.
Serial or USB to IrDA hardware off the shelf. Most PDAs do "IrDA" intrinsically.

Why are they stuck on IR?

Irda works, but it's slow as hell, and very sensitive to aiming and
interruptions.
Bluetooth or Wifi is a lot faster and more reliable.

Microchip just updated their application notes with regard to
communication between embedded ir application and PDA... check the
'what's new' page. It should still be there.

First off...thanks to everyone for the suggestions.  I'll be looking at them over the week and so I can let them know what it might take to do this.
 
 OK...David...you asked why IrDA?  Guess its more of....thats what they asked for.  I guess as compared to putting in a RF application, its cheaper.  Aiming isn't so much a problem I think as they will walk right up to the machine and dump the data log and I don't think it will be all that much data.  Using a PDA or the like would allow a common built in interface, although I do imagine most new PDA's have BT in it, so thats an option, but way more expensive than simple IR.  There are alot of wireless chips that could be used just as cheap..aka..wireless USB that might work but the handheld device, and wanting it off the shelf, would have to have that ability as well.
