You would have to break the vlans and push security into the
apps/frameworks. Vlans are a way to control communication between machines.
With mesos, the machine is not the unit of work since they tend to all
become identical and managed by a single team. What matters is the security
of the frameworks running over mesos. This requires big changes in many
apps relying on vlans or firewall to "secure" their TCP connections.

You would have to start working on authenticating connections, use TLS...
Etc. The hardest one is that vlans prevent you from DOS (either accidental
or not) from another unauthorized vlan. This is harder to do with Mesos
since at the network level you will receive the DOS connections and have to
reject them higher in the stack.

Anyway you could also work out a solution with tagged vlans and iptables
that restrict access to the vlan from a specific user. Then you authorize
some framework user to use a vlan on all slaves or not.
