Have one.. use it.. no real problem, what they discuss in troubleshooting is
that other devices like other AP's, microwaves, pa systems, cordless phones
etc, can cause interference. A real hassle when you are in town doing a
presentation...

You may be misinterpreting one thing they do. (i'll try and make it
understandable rather than technically correct). They use the idea of input
and output memory buffers. If stuff is in the input buffer, it can be copied
to disk/sent to another device/xferred to the output buffer etc. Another
routine looks at the output buffer and send it to devices/disk/a third
device etc. Most devices use that idea, buffer in - buffer out, it is
usually just done so fast, you don't know it's happening and think it is
direct connect.

Both Linksys/Dlink/Hauppage and a few other new wannabes. I work for a
computer sales/repair place, get stuff free/reduced price for evaluation,
and do onsite training with what I bring with, and whatever is available at
the client. My pride and joy though is the Wap/router (linksys WRT54G, open,
(I use the SSID of PPin?? ), and the Ximeta 250 GB net disk
(http://www.ximeta.com/products/network_drives/netdisk/index.php ) (Ethernet
based hard disk, plugs right into the WAP/router, gives me 250 Gig of
network storage for anything including videos/digital pixs/documents etc),
have both in my briefcase, set it on the table and plug it in. Ap and
Network storage to go Like the Hauppauge MediaMVP at
http://www.hauppauge.com/pages/pro [...] iamvp.html Really cool, will
paste part of the webpage intro: MediaMVP: the coolest video product on the
Planet! Listen to and watch digital music, pictures and videos on your TV
set, from your PC over your home Ethernet LAN! Now available at Circuit
City, Radio Shack (some stores), CompUSA, Micro Center and Fry's Electronics

Carry that around and attach it to whatever the client has.

As for your q about appearing as a clients.. I think the above description
makes that a resounding YES!
