DotCloud Adds Support For WebSockets, Vertical Scaling And More

Here are the announcements on dotCloud's blog.<p><a href="http://blog.dotcloud.com/dotcloud-announces-native-support-for-websock" rel="nofollow">http://blog.dotcloud.com/dotcloud-announces-native-support-f...</a><p><a href="http://blog.dotcloud.com/dotcloud-now-supports-mongodb-20" rel="nofollow">http://blog.dotcloud.com/dotcloud-now-supports-mongodb-20</a><p><a href="http://blog.dotcloud.com/now-scale-vertically-or-horizontally-on-dotcl" rel="nofollow">http://blog.dotcloud.com/now-scale-vertically-or-horizontall...</a>

I wonder what info-structure changes had to be done to support WebSockets. Are they using experimental nginx support? Something else?

What are the limits to the vertical scaling? Can I, for example:<p><pre><code> dotcloud scale MYAPP db:memory=144G </code></pre> How much would such a thing cost, if possible?
