This setup would require a seperate arena, with a player cap of around 150-200 people and using only small to medium maps.
Overall, I'd find a solution that modifies the victory conditions in a way that takes the focus away from field capture much preferable tho.

ps: sorry bout yesterday, I gave up after the 4th disco

Bloody unreliable ISP, and then my neighbours decided to diss me for making too much noise with AH so I decided to watch Champions League instead and have a drink...
