Memebership payment gateway through VirtueMart=

Hi!
We Using Joomla 1.6 and VirtueMart with a payment interface to CertiTrade card payment system in Sweden.

CertiTrade have a opensource interface to Joomla - VitrueMart, and are cheap and easy to use ( www.certitrade.net/opensource.php )
It woulde nice to use same payment gateway for VirtueMart and CBSubs.

Question:

1. Plans to support CertiTrade in CBSubs?
2. Is it possible to add a membership article in VitrueMart and integrate CBSubs memeberregistration to pick this article in VitrueMart and trigg VitrueMart to perform the payment trough actual installed payment gateway (in my case CertiTrade)?

Plans to support CertiTrade in CBSubs?

Not that I am aware, but would be possible to implement once we've made an API available.

No, I suppose you could handle payments through VirtueMart and manually give the user a subscription from backend. You could also use the Offline gateway then instruct users to pay through XYZ and then active their subscription, etc.. as for an automated way to do this there is none that I am aware of.

OK
When is this common API ready?

Hard to create a own CertiTrade-integration in CBSubs?
Monfify one of your on gateways to use CertiTrade instead?
Is there some documentation o the support pages?

When it's done, sorry don't have much to offer aside from this. We're likely not going to open the API publicly either, but through a developers plugin instead. CBSubs is much more complex then CB it self and dealing with users financials a developer program would allow us to screen developers.

At the moment is impossible.

Monfify one of your on gateways to use CertiTrade instead?

Gateways are encoded making this impossible.

Is there some documentation o the support pages?

Don't understand what you're asking. There's no API documentation either as API is not released.
