Can windows do this?

my school is firewalled off. our webserver is given 2 ports. 80 and 554. I put ssh on 554 so to get to the network from home i can tunnel pppd thru ssh. However the other network admins want to be able to do this as well, currently i have them just tunnel the port/ip they want, for like vnc. but ppp or some kind of vpn would be preferable. any ideas?
