The egg, as you may know, is going to be redone as a more squat version to better fit the bounding box. Once it's in-game, we'll allow it to be built on walls, not just on ceilings and floors. This is largely because the Tremulous egg looks ridiculous when you build it sideways.
However, I'm more intrigued by the possibilities of the telenode. From what I've heard, there have been Tremulous mods that allow you to warp between them. This would actually lead into some very interesting tactical possibilities for humans, and would work very well with our build/resource system, which encourages you to make outpost bases. Humans could rapidly deploy themselves across the map, or address multiple alien contacts. The telenode could be made more expensive than the egg to compensate for this.
Either way, I really think that you should be able to choose your spawn location while waiting on the queue. This could be done via showing a scaled-up minimap and letting you click on the locations of various spawn points, or just cycling between them with the "[" and "]" keys. Would this be feasible?
