We aren't using Business::OnlinePayment because we predated it. Had
it been in full flower at the time we needed it, undoubtedly we
would have used it.
We usually look closely at a module before basing our stuff -- it is
easy to get burned by using a module too early. Sometimes, as in
SQL::Statement, an incompatible interface change happens. We don't
like to have this happen -- sometimes, as in the case of DBD::Pg
(which started using runtime requires) we have no choice but to grin
and bear it.
By the way, we know and greatly respect the author, Jason Kohles. He is
an ex-Red Hat employee from the Interchange group and has done quite a
bit of work on Interchange.
Looking at the code, it would not be too difficult to build what
you said, a bridge between IC and Business::OnlinePayment.
The biggest problem I see is that there seems to be no constraint
on data format -- it is left up to the processor module to determine
in all cases. This is a problem for portablility, obviously -- if
the expiration date we provide is "0606" and the module expects
"06/06", we aren't really generic. And looking at the AuthorizeNet
and LinkPoint modules, they use incompatible formats.
