did you have a look at solidcoins? there is still bounty available for few more sites accepting solidcoins as payment
AyarikuBazar.com accepts namecoins and ixcoins. The payment will be done manually as I have no automated payment module.
To cut my losses I have set the rates:
1 NMC = 0.029 BTC
1 IXC = 0.00077
I will wait and see how many of the early-adopters of IXCOIN and NMC (that have tens of thousands) are willing to actually use it as currency and not only speculate. I can bet that the sells will be low or 0 but I'll wait and see.
Feel free to comment.
