First of all many members use dentoo services with success (as well as other seedbox providers in all fairness). Dentoo has very good prices and excellent performance and best of all, if you enter the promo code mmatorrents when you make the order and first payment you will recieve a recurring 10% discount so that it is even more affordable for our members.
The tracker does not work over IP but with the passkey added to the .torrent when you download it from your account. This means that you can seed from several locations (not same files though, one torrent from each location that is) as long as you have the correct passkey (aka have downloaded the .torrent file logged in with your own account) and the stats will always be counted correctly towards your account.
I defenitely recommend http://dentoo.info and personally garantuee that you will recieve the best support and performance ever
