..I have considered using contacts, but didn't want to bloat the wallet with potentially hundreds of contacts...
I'll use the reverse lookup - as I take it from xeroc's comment ...
If I use blockchain_get_account BTSX6LntkCfDLvwPrr13az5kYmivVYnJrSA7pmNF9kxNFFjeMqDgE7 , it will forever and always return nethyb as the register name.
thanks.
