If she is on the 6rd deployment I think she is, the gateway itself is getting a 
/60 from 6rd. The limitation is not 6rd or the ISP trying to be stingy per se. 
The limitation is that the gateway currently isn't sub-delegating to subtended 
routers, and the LAN ports are bridged and served by the same /64 anyway.

The current policies in ARIN and RIPE are such that there really is no excuse 
for an ISP to limit to /64 with 6rd, even without resorting to multiple 
domains. I don't know of any large 6rd deployments that are limiting themselves 
to /64 within the mapping rule itself today, but I've stopped keeping track now 
as it has become rather widely understood and available.
