Running vim as a server without X

So far, running vim as a server without X is impossible as far as I know. I don't understand why vim depends on X at all, especially for this case.

$ vim --servername foobarbaz
doesn't work, and even worse, silently fails. No warnings, errors, etc.

I thought it could be that vim didn't have some kind of compile option, but:
$ vim --version | grep client
+clientserver +clipboard +cmdline_compl +cmdline_hist +cmdline_info +comments

The only way to use vim's built in server is to give it a valid DISPLAY value at startup. This makes vim behave a little slower, which is especially noticeable at startup.

DISPLAY=:11 vim --servername foobarbaz

To start a server:
DISPLAY=:0.0 vim --servername mainVim

To edit a file on an already running vim server:
DISPLAY=:0.0 vim --servername MAINVIM --remote-tab-silent `find -type f -name filename`

Compiling GNU/screen with vertical split support

Yum (on RHEL5) GNU/screen doesn't come with the vertical split patch. We just need a newer version.
git clone git://git.savannah.gnu.org/screen.git
$ cd screen/src
$ ./autogen.sh
$ ./configure
$ make
# make install
