I think having such a shared server for all players is certainly appealing. Many fleets won't need this anymore, but it is still useful for the OPvP tournament events, I think.
That said - don't expect miracles - many people (including me to some extent) are shy, and their can also be language barriers in play. So some people will either refuse or shy away from the service. But having it out there as an option sounds good to me.
Is this just for events, or daily usage as well? If it's JUST for events/meetings, then I think a group Skype call could suffice (or even using an existing fleet's Vent).
ideally it wouild be for daily use and group use. this would require a large server that makes eevryone happy.
if this is something everyone can agree to use (not be the only one mond you but willing to make use of it) then i think tsi's current vent can be upcounted and channels added. we'd just need a teamspeak3 if thats whats decided.
mind you too that whoever is willing to take this upon themselves will be taking the cost as well (except those donations that are provided)
