Make a brush, texture one side with the hologram. Set it to func_illusionary and a solid render mode.
I think. I'm not a mapper.
Best place to find out though would be <a href="http://www.valve-erc.com" target="_blank">Valve-ERC</a> since we're mostly here to help people with NS stuff, like placement of resource nodes or how particle systems work. Stuff like that.
The way I do it is to create two func_illusionaries, side by side, completely covered in the null textures apart from the sides that touch each other. These sides are textured how you want the hologram to look (form both sides) with the render mode set to additive. The end effect is an infinitely thin hologram positioned where the two boxes touch each other.
Good luck with your map <!--emo&:D--><img src="http://www.natural-selection.org/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt=':D'><!--endemo-->
Hmmmmmm, sorry should have mentioned that <!--emo&???--><img src="http://www.natural-selection.org/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'><!--endemo-->

Noone'll notice the 1 unit gap unless they are REALLY looking, and it saves on planes and brush entities.
I'd personally go with the single-brush approach unless I was being really anal, in which case I'd go a small step further and use a "diamond-shaped" brush (manipulated cube), made one unit thick at its' widest point, to avoid the gap that having a 1 unit box leaves.

<------- Imbecile and proud of it.
I'm thinking about making a holographic projection of the map's layout at the marine start.
