pretty good. The one thing to keep in mind is that the free servers aren't dedicated to run all constantly and spool down after a period of time. They then spool up when accessed but it can take a few seconds
not sure on memory or processors. Probably depends on costs.
Ok, I've got the OpenShift project up and running. http://channelwormdjango-channelworm.rhcloud.com/ let me know if you see anything I missed. I had to add a few things to the ChannelWorm repo to make things work. The static files have moved to ChannelWorm/wsgi/static and the project is now under the ChannelWorm/wsgi/channelworm folder.
