Which version are you using?
I've recently made 4.8 available, to go with ComSwiki 1.0 gamma, which
now includes StaticFileModule in 'kom-demo'.

Some previous versions of Comanche included code in FileStream and
FileDirectory that did a similar thing, but since Swiki uses its own
file serving code, this was dropped.

With StaticFileModule, the default document directory is htdocs in
your Squeak directory. You can change that by changing its instance
variable.

BTW, RemoteDisplayModule was renamed to DisplayCamModule.
