Use the fake-files style to offer `a:/' etc. Then use an
implementation of _first that makes compset -P '?:/' and calls _files
with -W. Does that work?

I'm not exactly sure what this does, but maybe it could be done with
some more fiddling with _first (I mean: completing the server names)?

That's just an additional value for squeeze-slashes and a bit of extra 
code in _path_files:298. I think.

Use the matcher style? (Not matcher-list.)

The matcher style with `zstyle -e'?

But the solution may be similar to that for 1, i.e. a bit of checking
in _first, and fake only `a:' etc, not `a:/'.

I once said that this may be hard. But maybe it can be made simple:
just convert all backslashes to slashes before completing >:->
