The thing here is.. It's _fast_. I only have a dial-up at home and it's
sloooooowww. Painfully slow... If there is a way I can secure/tunnel the
connection to yahoo, that would be great. 

Otherwise, I need to know what it takes for someone with a little bit of
know-how to use ethereal or some other packet sniffer and grab the
pass/login combo.

There's nothing much in my webmail account, but I would still like to know
that it's not transmitted in plain-text. (which It is not) Even so, It'll be
nice to know what it would take for someone armed with a bit of knowledge
can do with the hashes.

AS I said, does Yahoo specify which sort of algo to hash the password? I
believe it's client-side but there has to be an understanding on which algo
to use. No point bein server-side, if it is then I'm screwed, all my info is
transversing through the wires/airwaves for _all_ to see.. :)

But hey.. if it's not a simple solution.. then.. I think I'll still use the
wifi..

I would hardly do anything WIFI unless it was encrypted.  And I don't
mean ROT13 encrypted, I mean SSL or so.  But then, I'm paranoid!

You could ssh from wireless laptop to desktop machine, which would very
securely encrypt everything (even plain text stuff) between then two,
and then use the desktop to connect on through the internet the way you
normally do.

If I were you, I wouldn't be connecting to anything that wasn't https
anyway, WIFI or no WIFI.
