Assuming you're in the U.S., you'll need to provide your MySpace credentials at the border when you return from your on-site interview in Paris for this REMOTE position. So yes, do polish it up, and also polish up on your "Strong proficiency in French and English" but be sure not to use the former with the border authorities.
I'm not sure if you're replying to me or the company. I have nothing to do with the company, I'm just some random developer wiseguy. I don't see any mention of needing experience with the latest LULZ stack in the posting and I suspect it wouldn't be compatible with ICE. There are worse things than being stuck in Paris with plenty of lulz I would think but YMMV.
