Does that mean we could offer full WMS capabilites and are not doing it
only because we don't have a suitable machine to host it?

If you're happy with the one projection that we offer, and if you want
base maps for the web, then yes. But if you're a GIS guy creating maps
somewhere, you will want to import your base map in the projection you
need, maybe even with some layers selected and some deselected. That's
obviously far superior to having just one base map, in a limited number
of zoom levels, with layers and projection selected by the renderer (and
As faw as I am aware, you can have this flexibility currently only if
you install Mapnik yourself and tune the styles to your needs. This is,
again obviously, something that 95% of people who might want to access a
WMS service cannot do.
It would be very cool and a giant step ahead of our "competitors" if we
could offer a full WMS base map.
Of course tiles are easier to do but they offer only a fraction of what
a proper WMS service would.
