I hope you're aware that pptp connections (including via poptop) can be broken easily.

Thanks. Fortunately I don't really care if it's cracked - I only care if I can have access to the western internet, and that works just fine.
OpenVPN has an AMI that you can install on an EC2 Micro instance which works fine as long as OpenVPN in general works -- which unfortunately is no longer the case as of the past few weeks.
Any suggestions of software that would deploy images to various cloud services on behalf of users? I don't think China would be able to block all of ec2 and Rackspace, though they do sometimes seem to throttle ec2.
