Some considerations:
* Lion uses more than one partition, it has an hidden partition called recovery partition, and so does Windows 7. So be careful with that.
* Google for a guide on how to triple boot with OSX Lion installed.
* As for licensing, AFAIK I don't think it has to be a Bootcamp partition, Windows licenses are related to the hardware, the computer, it doesn't matter how it's installed.
* As for not using Bootcamp Assistant, as far as I remember all triple boot guides start by using bootcamp assistant, I think the logic is to make it create a partition big enough for later being divided into 2 (Windows and for Linux) by another tool. Another tool that might treat GPT correctly is iPartition.
