i really like your idea and enjoyed looking through all the different companys out there.
not many in the uk though... which is where i am at the moment making a start on my own bitcoin business/project.cryptocredit.co.uk and cryptocreditphones.com  its early days yet but hope to be listed soon with a new website and trading platform on cryptostocks.com who i thought were based in china not germany as at the bottom of their site have a line that says brought to you by the developers of vircurex who are chinese for sure.
 i like the fact that you can scroll through the data  checking out who is where ,then click the link to open a new window give them a quick veiw over then go back to scrolling the next all in one place.
anyway i hope i make it to your data list as a successfull company trading mobile phone top up voucher codes for bitcoin and most importantly vice versa   with a small trading commision either way . i find most of the companys trading are all exchanges or wallets with not much to actualy spend it on especialy in the uk when shipping from far away is so expensive .
i would like to see the data more catagorized/ localized so i can see who is selling what at least in my country and search by country or even province.
phone top up voucher codes are a needed product that most pay as you go customers use only because they dont have a banking account to set up a contract phone . they also find it hard to obtain bitcoin unless going to ebay using paypal and paying through the nose for it .
then they could meet up in person using localbitcoin which is a bit ironic  considering this  digital age with superfast digital money  .
i imagine anyone going to the local store to buy a top up voucher code and using that to obtain an equal amount of bitcoin  making derivitives of the comunications network a currency in itself that can  be exchanged on a platform instantly for bitcoin. no need for a bitcoin atm or a bank account .
just need more companys selling products rather than exchanging back and forth continualy speculating .
 think you done a great job of listing them all and i am sure this is going to be an esential part of the bitcoin ecconomy as it grows . all the best jasont
