Don't worry. I'd never dream of using an unencrypted connection for anything other than e-mails, and even then I don't send anything of any importance over it.
I admit that I have occasionally piggybacked of unsecured connections, but this has been extremely rare as 99% of the time I either use a dongle (if one is available for the country/area where I am, or I will use the internet provided in a hotel or internet cafe.
The main reason for my earlier post was simply to let gehenna know that they may be able to access the internet from an internet cafe near to their hotel without actually having to go to that cafe every time.
If you can find an internet cafe or other place fairly close to your hotel which gives you internet acess using wifi, one of these may help.
As internet cafes usually have a secure wifi and a password and user name is required, this would still need to be paid for so accessing it from a hotel room or somewhere similar wouldn't be in any way illegal.
