Not if you're the host. I've never really had FSOD problems, except back when I played on DC. Only person I've FSOD'd on here is Lust, but that's because he is sometimes in field when I join his games. Always have everyone on Pioneer before joining. It only takes a mail to let everyone know, so be sure to let people know you're joining, or just lock your games and have people mail in case someone isn't in the know.
On another note, PC should always host for stability reasons, and should lay down a pipe because of a bug that happens on sylverant that makes quest start act strange. Also wait for people to load in Falz Memorial, or boss fight will desync. I think the severity of these desyncs is unique to this server software, but at least all the problems are preventable with enough precaution
