I say none of the above ..
In fact, server solution disc is never a very good idea. Most people that run a server have the expertise to install software themself. To bring vector onto servers I think the distro first needs more hardening and more server side support inside the kernel, as sysadmins want a scalable and easy to implement solution. If you run one server, you can put effort in tweaking the installation to the max however this is a bad idea since one day you will need a new server and then you have to do all work over again. Also upgrades are a pain for vector as you will have to reinstall the distro and all of it's software. That and not the lack of server software packages is the problem for vector server side. This last one is very very very important. After one year you need to update your installation for the sake of security. You need new technology.
As far as gaming is concerned, I have never been a fan of gaming on linux. The games generally are a bit minesweeper/arcade mode, with the exception of a few decent releases for linux, although only Wolfenstein Enemy Territory can be seen as the only free game around.
Development: same story. If you want to develop on vector you either go for vi or install k(web)develop, all in the repo.
Windows to linux migration service: well, might have a potential, only I don't see that as a real task for a bonus disc, unless someone could provide me some more information
