"Okay, the main thing would be, does it get traffic, now?"

Yes they do
not much but they do

despite the fact that this is a good question, it may not be the most appropiate one at this point in time.

If these domains were getting a lot of traffic they would be on the mainstream secondary domain market and, then they would be worth a lot of money by now.
(and we wouldn't be talking about it in this forum)

so here is what we need to consider regarding these of domains
1. how are they working now with IE7?
2. what is the value of the domain for branding?
3. since you can not register these type of domains anymore, are they any more valuable?

it seems vey unlikely that anyone would type an € symbol followed by latin characters in a browser, so only an intensive PR or a lot of luck will unveil to the general public these domains.

it happened with £.com so is just matter of time.
