Silent login to prevent page reload

[cosmopolit]

Hi! I want to combine hashover to work with our existing system. Users should be able to post, edit and delete their comments when logged in to our the magento system,

For now, when the user will visit a page with comments for the first time, i programmatically fill and submit the ho form. The crux here is, that the page will be reloaded once to refresh the hashover form.

Is there a possibility to login the user silently, as example to submit the "login ajax request" to just create the session data? A best practice for this most-wanted scenario would be excellent.

Thank you very much.
