To expand on vet's post.
º The dedicated server files are apparently at 1.1 GB right now.
º They are shooting to be released "within 2 weeks"
º Servers are able to bind to each IP and you ARE able to run multiple instances on one box...however there are no custom game ports as of now. I know in the confrence call some of the UK guys were saying they need the custom ports because they dont run multiple IP's per box. However alot of us US guys have more IP allocations available to us and custom ports dont matter.
The call was pretty broad and still alot kept in the dark...hopefully more info to come soon.
