Protx Contribution Questions

Hello,

I am interested in the Protx Payment Gateway Contribution and have two questions:

        1. What version(s) is it compatible with? 
        2. Will it be compatible with the next version released?
        3. Protx has three main VSP options: VSP Form, VSP Server and VSP Direct. 
            Is this contribution compatible with VSP direct?

Thanks!

Check out line 100 in catalog/extensions/payment/protx.php

It uses VPSProtocol 2.22 and the gateway looks like vpsform isin use:
