I remember asking that question back about multiplayer and got a response that it is possible to do multiplayer though daisy chaining and LAN from Shmup forums:

So far, I noticed that the pictures have the 1 player setup for location test purposes from the twitter. However, is it possible for multiplayer to happen depending on the number of player controls on the cabinet in addition to console link-up (like LAN connected to multiple cabinet machines)?
Assuming that the EXA Arcadia launches, still allows for cart changing, and custom local multiplayer is implemented, do you plan to allow developers to design custom cabinets to support any number of maximum players (4 players, 8 players, etc.) per cabinet?
I am sure that Exa Arcadia has potential to be an excellent social platform in its own special niche.
The JVS protocol is fully supported which means you could daisy chain 4 IO boards for 8 players but there could be inherent lag with such a setup.
I am only aware of 3 games that chain JVS IO boards for 4 players or more: Beach Spikers, Virtua Tennis 4 and Pengo.
The other way to go about this is via LAN but that would need to be fully implemented by the developer.
If a developer wants to fund making their own cab design and production, we would be open to it but it's not a cheap endeavor.
Over a year later, I am still excited for the possibility of multiplayer. There is so much that can be done with EXA Arcadia multiplayer.
I wonder if it is also possible to use wireless mode to search for the nearest available cabinet? If not, then I understand.
I am curious to know how a daisy-chain between two Exa Arcadia units look like.
I wonder if the maximum number of players per Exa Arcadia Unit is 4 players because there are 4 player games announced? If more than 4 players per motherboard, then great!
One more question, if 2 or more daisy-chained Exa Arcadia units are together and have various cartridges inserted, will the OS notify which games have "link-up multiplayer ready" for games that have the same cartridge or would the host machine with the cartridge send that link-up signal to other connected units without the same game?
