Just poking around on the Blosxom website, and came across a link to Blapp which is a standalone blog manager for Blosxom.
It seems like it's rather complete, but a wee bit rough - good enough, though. It also appears as though it will support exporting of the Blog to static HTML, so I can publish on .Mac.
Blap WILL publish a Blosxom site to any server, but it still requires Blosxom to be installed on that server. It doesn't generate static HTML, but manages transfer of modified files to the remote blog location.
Blap is an open source project now, with a home on sourceforge
