 I would do concurrency using hotplug, it's easier. Maybe we can add
 it to the libusb code in the future.

 uhm... I don't like it so much... Andrew?

 I'll give it a look.

 I must admit I can't remember ;) I'll give it a look...

 not everyone uses daemon mode. why do you need a pda block in daemon
 mode?

 Anyway, I use this system to handle my users:

 I create a real user with this directory tree:

 realuser/palm01
 realuser/palm02
 ...

 Then, in the .coldsyncrc, I put:

options {
        CS_DOTPALM:             "$(HOME)/$(CS_PALMUSERNAME)";
}

 so each palm gets his own directory.

 In the libusb code this almost works...  :D
 

>  - databases with over-64kb records must be supported

 I agree. Someone can please send me such a database and
 tell me which version of the Palm OS I'll need to 
 properly use them? 


 Anyway, I'd like to release 3.0 as is and then made some
 more corrections in 3.1.  I'll see if I can test
 the libusb code with a T3...
