We are planning to use stripe payment processor with CiviCRM 4.6.x and are considering using it in Drupal Webforms. Currently the extension is only marked as compatible with 4.5 but there is a 4.6 dev branch on github.
I was looking into stripe in combination with CiviCRM <--> Drupal webforms and found that there had been issues, described here and here. I was however not sure if those were resolved (as indicated by the Drupal issue) or if there are still problems as the Github issue is still open.
I tried to contact Drastik on the stripe payment processor blog but the spam protection wouldn't allow me for some reason. I also tried the contact form and email but got no response.
I would love to get some feedback on 4.6 compatibility from the developer or anyone who has tried it.
