I just did a little test-driving of Flow http://www.near-time.com/PRODUCTS/flow.htm and now I’m wondering if there is any chance to built just the publishing engines (FTP, WebDAV, RSS, Weblog, Email) into DT (via scripts)?
More publishing possibilities are in the pipeline, e.g. version 2.0 will probably include blogging support. And one of the next betas of DT Pro will include a new export plugin to create simple websites.
