I would hope so. I think it would be easy to provide a facade with the current API that uses Zinc.

If I remember correctly Sven has tested monticello from an early stage on. And it seems to be a reliable thing to use.

What do you mean? The HTTP classes in Network-Protocols or http the protocol) :)

I don't like the current API at all and I'm glad Zinc is different. But for legacy purposes a facade should be easy to implement that resembles the existing one. On the long run some of the calls should vanish and only the httpGet: and friends should survive to offer a really really easy and basic access to http.
my 2 cents,

I would like to see it that we don't talk about HTTP but about proper MIME based communication. I think the very core that is in there is the structured and flexible mime media handling and communication. And this is not only true for HTTP but also for email.

Than the mime stuff should break loose of the Zinc components and should replace the mime handling that is in the image. Than we have it for http and for mail sending and for every other transport protocol you can imagine.

The same problem goes for the WARequest stuff. Using zinc you can get access to the mime parts. Now WARequest is a strange request object that contains a dictionary for request parameters and a raw message body. If only compatibility is important than a zinc to old WARequest handling is needed. But I would like to see the mime based handling to be the "normal" way of doing and not vice versa. But I can see that it must be a special treatment as seaside is ported to so many platforms that don't have zinc. Probably one reasone more to extract the mime stuff. It might be a promininent candidate other platforms adopt.
