Mike Cardwell over at grepular.com (referenced in the post above) wrote a pretty good post about the issue too. It is not beyond the realms of possibility that telcos are generally "discouraging" encrypted tunnels of any kind. So even a VPN may prove problematic. It may be worth experimenting with corkscrew to tunnel ssh over https (thus hiding the fact that you are using ssh).
I find generally VPN's work ok these days on both public WiFi and mobile data connections. They are often used by the business customers and therefore pretty much need to be supported. SSH is different because its use is really only prevalent amongst the techs.
