Syncronize 2 Pocket PCs via bluetooth?

I am thinking about picking up a PDA for myself and my fiance(HP 5555 for me and 1945 for her). One of the main things I want to be able to do is sync our 2 PDAs with each other and not have to go through a PC to do so. Also, my PDA will need to sync with my Outlook at work(I know this wont be a problem.

What I will want to do is to sync with work and get any new calendar events on my PDA. Then, when I go home I want to be able to have the bluetooth auto sync(if needed a manual sync will be fine) our calendars. It is fine if she gets all the events since most of our personal events are on my work calendar. I do not want to use Outlook express on the PC or even have to do active sync through the PC since why have a middle man if both PDAs have bluetooth and can already talk to each other in the first place.

Please let me know if anyone knows how to do this or knows of a program for the PDA that will allow this "adhoc" type sync of our calendars.
