Hello Henri,

I'm not sure.  Do you have a synchronized folder into which you can drop files and have them show up on another Mac?  This is what Dropbox does.  If so, then the answer is that you would simply move your .bkmslf file to that folder and it would work like Dropbox.  However, if the WEBDAV software does not do incremental file syncing, then you will find that BookMacster may generate excessive network traffic, because every time you change a bookmark and save the file (or OS X Lion autosaves) it will send the whole bookmarks collection which is typically a few megabytes.

Sorry for the technical answer, but we've just not looked at WEBDAV servers very much.  Our next project in synchronization is, of course, to update BookMacster to support Apple's new iCloud service.
