[Zope] eCommerce with Zope

[Ragnar Beer]

Howdy!

I wonder how on-the fly verification of e.g. credit cards or whatever 
else verification that could take some time can be done using Zope if 
Zope doesn't support multipart content.

As a user I'd expect to get an immediate feedback like "verifying 
your credit card ... (please wait)" or "checking whether this domain 
name is available ..." and then after a while see the results without 
any further action. This is would be a typical job for multipart 
content-type, wouldn't it?

Is there a workaround or so to get this done with Zope?
