I first thought of this:

http://vim.wikia.com/wiki/Display_output_of_shell_commands_in_new_window

But it looks like it won't work for your purposes, because you want to use lines in the current buffer as input to the external command.

You could probably use :'<,'>w !asciidoc ...

But then you'll need to put that output into a new buffer somehow.

Probably you can :'<,'>w !asciidoc ... > somefile.html

and then load somefile.html into a new buffer.

Or maybe, asciidoc has an option to write to a file?

Anyway, the relevant help is :help :w_c
