Everything depends how complex frontpages you will need and how complex publishing flow you will use. If you plan build website where frontpage layout and content does not change very often then Website Interface (ezwebin) is right choice.
But if I use ezwebin, I loose the media capabilities of ez flow? I could use them on parts of the website though. Is there a way to have front pages from ezwebin, but still have the opportunity to use ez flow pages on parts of the website?
You can move media (flash player, recorder) to your ezwebin installation. Just export classes, move templates and override rules as well as flash module. Then add it to ezwebin installation. It shouldn't be so hard.
It's really a pitty that both features (or their packaging) are mutually exclusive. It would have been great to have standard frontpages and flow-frontpages available for the same website.
As for your proposed solution, I'm not sure I'll go that way. It might seem super easy for you, but not for me. and I'd prefer an install as standard as possible to lower maintenance efforts. That was also my primary reason to look at ez publish, as a lot comes out of the box.
Could you please expound the differences between <b>Website Interface</b> and <b>eZ Flow</b> detailedly? I didn't find where is the related documents.
I submited a post on this question, but no response for several days. Could you please look at it when you have time? http://ez.no/developer/forum/extensions/ez_flow/questions_on_website_interface_and_ez_flow#msg161844
