Not only that, but the information there is misleading, as one doesn't really need to use an ssl socket to connect to paypal, as there is no financial information (i.e. credit cards, bank accounts, etc) being passed during the IPN exchange. Therefore, since vBulletin uses PHP, using a perl script to integrate would be alot more code involved to get perl to talk to the vb php backend properly.
That, and that script doesn't help me in the versign signature authentication, and that's the #1 thing I'm worried about right now, because I can "spoof" the script with a proxied form using the right variables (i.e. it will accept the variables and such, but when talking to paypal for verification of the data, paypal will always send an INVALID string since it did not initiate the call.) With the verification of paypal's verisign sig, I wouldn't be able to do that.
Thanks for the help though
