I do have some definite ideas. The CyberCash model on MiniVend takes
care of most of the integrated payment needs. The ability to return
a hash with result codes makes it fairly general. If you want to use
integrated payment, I recommend writing a CCLib.pm compatible module
to use with MiniVend. I have written an example which links
to PaymentNet:

	ftp://ftp.minivend.com/pub/CCLib.pm.paymentnet
  or
	http://www.minivend.com/minivend/CCLib.pm.paymentnet

The advantage of this approach is that you can change payment systems
with only configuration file settings; the same form interfaces are used
every time. Though it would be difficult with the current implementation
to use multiple services on the same MiniVend server instance, that
would not be too difficult to change.
