If you’ve landed here with an iPad, I’ve managed to activate OnSwipe on this MU WordPress blog. I have posted instructions for others that wish to do this at http://wordpress.org/support/topic/plugin-onswipe-instructions-for-onswipe-10-windows-server-2008r2?replies=1
Please note that the OnSwipe folks do not support Windows. If you do want assistance, post in the wordpress.org forum.
