Full Disclosure: I work for a payment gateway, though I'm not really any
good for technical support thereof.

Authorize.net seems to work on the basis of a relatively simple
HTTP-based protocol that anybody can implement. Feature-wise I don't
know what they're capable of, but look into Payment::Authorize at
http://rubyforge.org/projects/payment/ (or gem install payment) for the
simple cases.

PayPal's Express Checkout can be implemented via SOAP calls; SOAP4R
(http://dev.ctor.org/soap4r) or ActionWebservice might serve you well here.

VeriSign Payment Services (now owned by PayPal) provides a binary SDK
for most platforms, with a boatload of features, but no Ruby bindings.

Those are the major gateways I'm aware of. There's a ton of other,
smaller gateways out there, but I expect those major platforms are the
ones you're most likely to find others have implemented successfully.
