Wow, so I tried this tonight and ended up selling a cam show to some guy on SL. I posed as an ewhore chatted him up and got the sale.

So I suppose it works. I can't see making a lot of money actually doing the ewhoreing in SL though since the conversion rate from Linden dollers to US$ is very low. You'd have to suck a lot of cyber dick to make any real money.

One other problem I noticed is that you can't just block someone after you sell to them. So if you send them to a girl that is not really "you" and they find out, they may get pissed and harrass you about it, or tell others not to buy from you until you make a new account.
