Clever idea, but it won't quite do what they think.
1. It will not give one the ability to download at 324 MBits/sec from
one web site. The speed limitation will first be by the wireless
connections. If 802.11g, and very close, the best that can be done is
25Mbits/sec per connection or 150Mbit/sec total. I don't know of too
many public access points running faster protocols.
2. Outgoing bandwidth will also not distribute equally among all the
6 connections, but will try to cram everything through one ISP.
3. There's the not so minor problem of self-interference. The 6
cards are unsynchronized and there will be collisions. There are also
only 3 non-overlapping channels, so every usable channel (1, 6, and
11) will have at least 2 radios on the same channel.
4. The connection to each ISP will all have different IP addresses.
Without a method of bonding all 6 streams together into one stream,
the maximum download speed for any single download will be the speed
of the fastest ISP connection, but no more.
5. You can do the same thing with a load balancing ethernet router,
and 6ea wireless ethernet bridges. With separate radios, you can
optimize their location for best reception of a specific wireless ISP.
Bridge radios are about $50/ea plus $500(?) for the fancy router:
