Is there an adult processor that can do any of this?
 

Is there a processor that will allow you to sell someone credits, not a 'membership'. For example the surfer could pay $5 via a form just like a join page, but instead of receiving access to a 'members area', the processors script will communicate with the site that they have just loaded money and they will get credits to spend.

Or

Is there a processor that can accept penny transactions?

Or

Is there a processor that can allow you to accept varied transaction amounts ($1.00, $1.01, $1.43, $5.87, etc..) and not just the few options you would provide for a join form?

There are lots,

But the best is www.vxsbill.com

You should be able to do this with about any processor

if your using micro payments, look at phone billing
