Great idea, but tbh would prefer if it were GUILD WIDE. It be brilliant to have a centralized area with a mail box, guild bank, etc. Also, just for those daft guild things (group pics!). It would be much easier to meet up with a guildie (for a trade, inspection, check-out the ridiculous outfit I'm sporting, etc.) instead of finding where or which server... just meet up at the guild ship (or whatever housing).
I see great potential, just hope the technology and Bio-minds can create it!
Cheers!
