it prefixes the socket.name with "?_send;_beam:" to pop up a system
dialog asking which transport to use. If I want to explicitely use Bluetooth, my
Palm OS Programming Bible tells me to use "_btobex://?_single/" before
the name. But that doesn't do anything: the data still gets beamed over IR (as
tested on a T3). What's missing?

BtExgLib.h has defines for the BT exchange library. I think you want 
btexgSingleSufix which works out as "?_single/"

the "?" tells the exchange manager to prompt the user if multiple 
libraries are registed to handle the same scheme (i.e. "_send")

The exchange manager uses the scheme to work out which exchange 
libraries it has to use to send the data. Each library registeres one or 
more scheme with the exchange manager when it is opened.

You can write a shared library to handle sending data via the serial 
link. It must have the same interface as all the other exchange 
libraries. (see ExgLib.h for details). We have had to do this for our 
mail application to handle sending attachments.
