WordPress.com has been blocked from China for many years. Nothing will change that. However, Videopress is not, and probably will never be blocked because it is a paid service.
I just paid for and started using Videopress for a website I help advise on in China. Videopress is fantastic and easy-to-use. However it has one fatal flaw for both using it from China and potentially using it from any company firewall or location that blocks access to WordPress.com.
The flaw is that to use it from my own self-hosted blog, it must authenticate via the wordpress.com domain. That is bad. That means it is inaccessible unless using a VPN.
I do not mean the initial subscription and linking to WordPress.com -- that is fine and understandable and can be done with a VPN. However, after we buy the service, and we try to drop video files in the Media Upload area on the Post creation screen, that iframe authenticates with WordPress.com.
There is a good, fast solution:
Authenticate using a different domain name by using a domain alias. I would gladly pay for the next 10 years of domain name registration for WP to buy a new domain for itself on which to authenticate. Or waht about a subdomain like wp-authenticate.videopress.com that is an alias of wordpress.com?
And there are perhaps other great solutions the community here can suggest to VideoPress. I do not want a refund on the money I paid for at VideoPress; install I want this to be a more-flexible product.
