Hi,
What do you mean by the jquery based device?
Generally speaking you should be able to use any jquery library,scripts etc inside Kentico. E.g. we are using jQuery mobile as well.
And also developers can indeed offer their application for Kentico on our marketplace
http://devnet.kentico.com/Marketplace.aspx which we believe will grow fast in the future.
Please let me know if you have some questions.
Kind regards,
Richard Sustek
