fortuniately for me i have system admins that dont know what they are doing security wise. it took them 4 months to track us down when we put doom95.exe onto the public server so that everyone could run it. the best way around bess is to get a flash drive. if the USB ports at your computer are disabled ur screwed
the best way to get around bess fully is to get a proxy
https://www.proxify.com works nicely for me if i forget my flash drive at home, i have a very fast proxy on my flash drive.
Mess with your system admins slow the internet down. if u have firefox or portable firefox type about
:config in the address bar and hit enter change the following values to true network.http.pipelining and network.http.proxy.pipelining then change network.http.pipelining.maxrequests to a really big number, the bigger the number the more bandwidth u get and the less everyone else gets
portableapps.com has a handy program called portable gaim, this allows u to access AIM, ICQ, Gadu-Gadu, Groupwise, IRC, Jabber, MSN, Napster, SILC, and YIM. this unfortuantely does not have talk from google, but since my admins suck they dont know that google now has a chat function and we use that to mess around too.
