I would recommend having an "OfficeHours" discussion if possible. The NethServer and SME Server teams should be involved. There are too many open questions that need to answered and a meeting is probably the best forum to get some clarity.

Part of our agenda: software stacks (ie postfix+amavis+...) kernel features
Packages we're building now: http://code.nethesis.it/
