It depends, the plugin has a strange bug over the internet where (it looks like) once a packet is dropped the whole system starts re-sending packets to everyone, and really breaks the game.
However, if you mean over a LAN, or where ping between players is around 100ms or less, then it should work fine I think.
I'll be trying to edit the plugin code that SciDave nicely open sourced, but until then a workaround might be to create a system to ignore repeat packets (store a list of the most recent 100 messages received?)
