No problem.  I have done this using a Linksys WRT54G (easily available
from ebay) running owfs on OpenWrt to provide a wifi remote 1-wire
hub.  You need to add serial ports to the router and use a serial
1-wire master or build a DIY 1-wire adaptor (see links below).
OpenWrt will only run on certain versions of the router, see the
openwrt website.  I have used version 2 which are quite old so cheaply
available on ebay.
