Extending wireless access across the street

Do you all see any problems in the following scenario. I would like to
extend my wireless network across the street so my neighbor can share
my Internet connection. We live in a rural area where DSL and cable
are non-existent and satellite will not work due to latency issues
(VPN). So here is my current setup and plan. I have an ISDN line that
dials into my ISP on demand; I have a block of static IP's for
internal use. I can currently connect wirelessly to the Internet from
my home. I have a Linksys WAP11 (bridged) connected to a Cisco 804
router. My wife and I use static IP's assigned to our wireless cards
to connect. Everything works great and there is no problem with
coverage at all. My plan is to connect another WAP11 in bridged mode
to the 804 via Ethernet and use a directional antenna like the one
from Hyperlink http://www.hyperlinktech.com/web/re09p.php to send the
signal across the street. I am not sure of the distance, but I know it
is close enough that with the WAP11 on my front porch I could get a
weak signal from the front porch across the street. Form there I was
planning on installing another WAP11(bridged) to pick up the
directional signal and pass it on to a BEFW11S4 via Ethernet. I could
then assign one of my static IP's to the Linksys router and his laptop
could pick up a private IP from the router and connect to the
Internet. What do you all think? Thoughts and suggestions would be
appreciated.
