Well, from what I've read, the ebay and cj affiliate programs will run together in parallel during april to ensure a smooth transition and nothing falls through. You shouldn't "feel" the switch other than maybe getting a new id and password, etc. along those lines.
For BANS, probably just some minor changes to your aff id...
Just read the above from a few different blogs/articles.
If I understand correctly, cashsalute's service basically just throws traffic at your site till you reach your desired number leads, so he has no control really over what happens with ebay and cj.
