It's a cool hack, but I have to agree with the previous post that it has no potential to a reseller. Does .in get any traffic at all? I do think, though, that if you could get pokerallin.com (looks like it's owned by another domainer), then it would be a pretty nice pair and could possibly have a good chunk of potential for an end-user... if you managed this and wanted me to help find an end-user, I'm on pretty good terms with the guys behind All In Energy Drink and All In Magazine. Unless you could get the PokerAllin.com counterpart, though, I think too many people would be typing that in and it defeats the brandability quite a bit and really hurts the development potential imo.
Of course... if you developed it to be an Indian targetted site, it's a whole different story.
If you can get PokerAllin.com, I'd estimate the pair to be worth about $300 to reseller and about $1500-$5000 to an end-user. If you can't buy PokerAllin.com, you should see if he'd want to buy the domain from you.
