It also requires careful evaluation of your firewall settings so as not to expose everything to any casual caller that might drop by.

Even if the IP address of the host machine changes after its DHCP lease is expired you can still do a Scan and connect to the host computer by name. I would do this for say a home network instead of using a static IP address. Also, when using a wireless access point you are right you have to be aware that you can expose information so you need to choose a strong encryption method, WEP as a minimum and WPA preferred.
