First I think you have a great thing going on there for CLN as far as hands on is concerned. Maybe with potential for expansion with more edge devices to emulate hosts etc
However I was just wondering since it's open, multiple people could be working on the lab at same time, thus screwing eachothers configuration with a potential for fustrations and conflicts.
Lets say, i am configuring a trunk port on one side at the same time some other guy comes in and configures an access port on the other side You might have thought about that already but you are still developing a solution.
The free lab now has 6 switches, and can be used to simulate Cisco's 3 layer model: access, distribution, and core.

I don't think I will add anymore. I might add some 2621 routers as part of a routing tunnel lab.
