Thank you for all the crossed fingers! I'll post updates to the project if we get the contract, and possibly open a website with a developer's blog and a beta version when the client agrees. Until then, we're under NDA and thus can't give information about the MMOG details or our potential client's identity.
To answer the technical questions, the server prototype so far is just a plain A7 pro with no extra network libraries or any other extras. The technical concept of the final server cluster however will be a little more complicated. There are alternatives to an A7 server, such as a Java based system like Terracotta or Darkstar. However, due to the tight development schedule we'll probably go with the classical approach.
We did not originally intend to go back to game development with a project of this size. We've never handled such a huge project before. oP group and Conitec will have to team up for this, and bundle their resources. Such a project naturally also raises questions in one self, such as: am I really up to this task? Three out of four serious MMOG attempts fail. We have good reasons to assume that we'll belong to the 25% that have success. Still, it's sort of exciting.
I'll keep you informed.
