A few questions:

(i) Does PayPal require that one uses SSL? I know that one should, but getting it going or changing hosts can be a lot of work and expensive.

(ii) Anyone know of a cc payment module/company that has a "secure" payment procedure without SSL?

(iii) Any known sequrity concerns with the built in credit card module in Zen-Cart? Anyone using it who has comments/experience?

All input appreciated.
