WMT has been running off toollabs for around a year now on a dedicated exec node and currently we're rebuilding the backend of it, rewriting the code and adding new features and functions as we go.
A labs project would be advantageous for us considering toollabs' state and focus at the minute and allows us to be more, controllable and easily expendable with how the project is allocated and designed.
Once the base of this is set up, it also means an exec node can be thrown back to toollabs for either deletion, re-use, re-creation or whatever.
