if it's locked down that tight, with only http connections allowed 
outbound and all those forced to go via proxy then of course it doesnt. 
But all you need is ONE outbound service that can avoid the proxy - I've 
had best results setting the vpn endpoint to use the https port, but if 
necessary, all you need is outbound ssh whether its proxied or not - you 
can "add a layer" and tunnel a ssl-based vpn over that. I know 
"tunneling a tunnel" isnt exactly best practice, and theoretically you 
could just tunnel the SL ports with ssh alone but the advantage of using 
a vpn is that it appears as a separate network interface to the local 
machine and it's therefore easier to route the LL public subnets traffic 
through it reliably. It's always easier to poke holes in a firewall or 
proxy from the inside out, they are designed to prevent unpleasantness 
coming the other way :)
