Regarding dan's post - I think he meant WGB-350 - I use these in external
weatherproof boxes (modified for POE) to run 14+ mile links back to AP350s.
The AP350s will figure out the wireless routing among their points, but as
Dan had said, they won't drive the wired (cat-5) jack when used this way,
so the WGB-350 or a network card becomes the end node product.  The only
limitation of the WGB-350 is that it does not handle more than 8 mac addresses
in it's table (above that you need to buy their "building to building"
bridge series).  If you attach a router to the wireless bridge, you can
get by with the least capable models from Orinoco, which only handle 1 MAC
address.  Essentially the number of MACs handled reflects the price of the
bridge products.  

There is a subtle advantage to using cisco's hardware (and I've tested a
wide range of mfgr's products) - the aironet/350 series is much more 
sensitive on the rx side and more immune to adjacent channel power 
problems.  Compared to the inexpensive 802.11 brands, it can have
as much as a 10 dB advantage on the receive end.  The transmitters
are all pretty much honest at 30 or 100 (and now 200) mw, but a link
with 10x improvement in receive sensitivity can make the difference
in a working connection or nothing but a fustrating day pointing
antennas.

A good tip when buying these for this application is get the single
antenna, permanently attached version of the wgb-350 (i.e. the cheapest),
then open it up, crack open the antenna (just the end of the rg-174 coax)
and attach a BNC or other favorite connector, and install a dc/dc 
converter for the +5VDC they want so you can use POE - this sealed in
a box can be mounted within 1-2 feet of the outdoor antenna and totally
eliminate long coax runs.  A few companies have made integrated versions
of what I described, but they are typically had at a cost premium,
and don't offer the cisco/aironet performance.
