Email setup in network

Hi, I've got a little WLAN network at home: desktop Suse 9.2 running samba and two ancient laptops both on win2k. I mostly work on the desktop, but have been known to use the laptop in the bath etc and certainly when on the road :-) My wife uses her laptop only. My question is: Can I use KMail on the desktop and save it so that another win email programm can read the mails for when I take the laptop on the road? Similarly, can I just overwrite the new emails folders onto the desktop when I return home? Or any other suggestions that would achieve a working setup? Ta Ingo
