Oh that. It hoses https too for Mac and Linux. I have only seen that idiocy on 
lame hotel pay internet ... 
(For some reason MSWindows is sufficiently non-standards compliant to adapt to 
these lame net appliance that were only tested with MSWin... . People should 
read the RFCs ...)

BTW, I think I've found a solution to my SSH sessions freezing at "random"

It's discussed and explained in the thread here: http://bit.ly/5Kh2PE

Summary: tcp window scaling* freaks out various types of old or stupid
network equipment. To disable it on the offending system, issue the
following command:

sudo sysctl -w net.ipv4.tcp_window_scaling=0

I don't know exactly where the problem is occuring in my case, but
issuing that sysctl on my laptop fixed the issue with ssh lagging to
the systems behind the PIX at work... but ssh sessions to my linode
server weren't fixed until I did it on that host as well.

There's also an article on this issue here: http://lwn.net/Articles/92727/

* introduced in the linux kernel around 2004 but not turned on by
default until around 2006
