[ic] Transparent Redirect for IC

[Grant]

Is anyone interested in helping put together a generic or Braintree
Transparent Redirect payment module for IC?  The basic idea with
Transparent Redirect is to post your credit card form directly to the
payment processor who then transparently redirects the user back to
your site.  This means you don't have to deal with PCI Compliance at
all.  I don't know of any downside to this.

Stefan has a working Braintree module which uses the conventional
server-to-server method instead of Transparent Redirect:

Dan has a working Braintree Transparent Redirect setup which he has
sent to me, but he says it's a little rough.  Another IC user has sent
me his working Transparent Redirect setup, but he also says it's a
little rough and it works through a different provider.

I can contribute some funds to this.  Can anyone else help with funds
or brainpower to finish putting something solid together, hopefully
for inclusion in IC?

As a side note Braintree recently released a client-side Javascript
method for encrypting and transmitting credit card data which I
thought was interesting:
