We already agreed this is probably a good idea months ago, and have discussed it at length on at least two occassions. Nobody has taken the time to do the technical implementation.
We've discussed and basically have consensus that we want the commander buildable in the strider hub, so that it's a regular unit. It would probably be built at level 5 so that they aren't a source of free buildpower.
There might be a limit of 1 per player (In which case you have to figure out what to do with captured, transfered, /taken and ressurected comms), though it's possibly reasonable to have as many as you like too.A bunch of mech level super-constructors with sniper guns is possibly not desirable, but it might at least be interesting to see what would happen if you can make an army of comms.
