Will Stripe Payment Processor work with CiviCRM 4.6 and/or Drupal Webforms?
We are using Stripe with 4.4.14 and had problems accepting payments for memberships using a webform. With investigation though, our developer installed a version of Stripe 1.9.1 from the github and the latest dev build of webform and it is now working for us.

Whether anything within 4.5/4.6 has changed to make our experience irrelevant, that I can not answer.

Whether it is useful or not, contrary to the information on some of the links you provide indicating it might be a problem with the webform module; in our case it was apparently the Stripe module that was the issue.
