  2. Well, you could use Google Groups to search for previous postings on
    the topic. However, may I suggest you disclose a bit more about what
    you are trying to accomplish and what you have to work with so more
    specific answer could be fabricated. From your one liner, it's
    difficult to tell if you want locations, security hints, construction
    articles, or hacking information.

    all BTs' roaing sites worldwide, may give you an idea what what that company
    does regards roaming.

  5. Well, I'm not sure what you mean by "connect". Your existing
    broadband ISP probably does NOT offer connectivity service in a
    different country. However, you can pickup your email from your
    existing broadband ISP from anywhere on the internet. Once you're
    connected to the internet, the rest is fairly easy.

    What Wi-Fi wireless does is connect you to the internet EXACTLY as if
    your were plugged in via an ethernet cable. It's literally a wireless
    extension cord replacement for ethernet. If you can connect by
    plugging in, you can do the same via Wi-Fi. Many hotel have both
    ethernet jacks and wireless.

    Like ethernet, you don't just walk around plugging into other peoples
    ethernet connections at random. Wi-Fi requires permission of the hot
    spot owner. Some require payments, other are free. Some cities
    provide service for free. Some individuals publicly share their
    connection. Usually there are signs or online directories that will
    give you a clue of what to expect. I'm not familiar with Australia
    and can't offer specifics.

    Once you've connected to the internet via Wi-Fi, you can pickup your
    email from your existing broadband provider. Depending upon
    configuration (POP3 before SMTP), you may also be able to send email
    via your existing broadband provider without changing any of your
    email program settings.

    However, there's a catch. Public Wi-Fi is unencrypted and therefore
    can be intercepted, sniffed, and abused. Your email logins and
    password are going over the air in plain text and can be captured.
    This is a major security issue and should be carefully considered.
    There are solutions, the easiest of which is to use SSL secured
    (https://) type of WebMail to your existing broadband ISP. There are
    also VPN solutions. Ask your existing broadband ISP.

    The same security issues apply to using credit card numbers via
    wireless, or sending or receiving any form of communications that you
    don't to keep private.

    You should also be sure that what you're connecting to via Wi-Fi is
    not a fake access point. See:
    | http://www.wi-fi.org/membersonly/getfile.asp?f=Wiphishing_For_Web_2.pdf
    If you can do most of your surfing or email using SSL (https://),
    you're fairly safe from sniffing. Also, be sure to setup your
    wireless laptop client so that it does *NOT* automatically connect to
    any random access point, but that it requires you to manually select
    the desired connection.
