Huh, what do you mean "I think the most easy way to accomplish this, is to
setup a wireless AccessPoint on a Linux host"
Your clients with their wireless network interface cards will receive IP's
from the Wireless access points and not via the Linux Box that you have
connected...if that is what you are inferring. But you may be able to port
this information to a linux box that is connected to your wireless access
point.
HTH,
