This does indeed look like a great idea -- it has the additional advantage of 
compressing the data before beaming it, which could lead to a significant reduction in 
the demands on users' patience.

Anyone interested in this undertaking (my company is, but I don't know when and if 
we'll get to it) should take a look at http://palmzlib.sourceforge.net/.

Of course, there are downsides -- most of them centering around memory demands, as 
Jeff pointed out in his original message.  It's my impression that ExgDBWrite makes a 
local copy of a database before beaming it, further increasing the demands on free 
RAM, on both sender's and receiver's devices.

A nice enhancement to this proposed mechanism would be an automatic launch of the 
self-extracting .prc on recipient's machine.  In principle, this is easy; just beam a 
dummy message to it once it has been received and accepted.  But I haven't figured out 
a way to delay that message for an appropriate amount of time so that recipient's 
machine is ready for it when it comes!  Seems to me that Application Launcher should 
have some way of automatically launching an application it has received via beaming.
