The RP scene in Vana'diel is a bit less than spectacular in that it's a dying art. Never having a RP server from the start certainly didn't help matters. There is a sticky in this section of the forums with RP linkshells in FFXI though.
Currently, there are only 2 listed, one on Siren and the other on Lakshmi. I do know that there are two more though -- one on Asura and one from Sylph simply awaiting advertisement details. Tsumi can shed more light on the currently unadvertised Asuran RP group when she gets the opportunity. Isilme knows about the Sylph one but has yet to even log in since registering, so that one may not get advertised xD.
Just keep in mind that all of these groups are pretty small these days in comparison to what FF14's RP community will be at the start.
