Wonder if either of us still has that wallet ?
I'm pretty sure I still have it.
I guess I'm going to check my old wallets for this game (not really for the reward, just for curiosity) and while I'm at it I will look for the aforementioned IP-based transactions.
EDIT #1:
I've been PMing and spreading this topic URL around, a few people here got it from me. 
yep, thanks for that 
EDIT #2:
Hey SmokeTooMuch,
Do you remember when you sent me 2x 0.01 BTC to test IP sending ?

Was this the first public Bitcoin transaction to an IP address ?

I just checked all topics with an ID <34 and none of them contains such information. So it appears that, in fact, this was the first public transfer-by-IP-address transaction, at least on this forum. I haven't checked the old mailing list or forum on sourceforge, so I can't guarantee for it, though.
