well, Mad Student :P
There is a way to check your hotmail account at school by using a different website. I found this out through my iGoogle home page. I added hotmail and I could access it through SurfControl and the proxy at my school.
The site is:
http://mobile.live.com/hm/
this is the hotmail site designed for mobil phones, but it works for computers also. The only downside is I haven't found a way to download attachments yet.
Hotmail is the only email that I have found a way to get around.You can also see if Yahoo! or gmail have websites for mobil users yet.
