Paxum is a great service, I use them for about 9 month on some occasions (when it's easier for a client to pay through them for example)
They are very responsive and have representatives on other boards, so if it gets traction here i'm sure they will be happy to handle questions on this board as well.

Only downside for me personally, is that they are based in Canada and EFTs/ACHs travel realistically speaking 5-7 business days from US, wires a bit less.  Loading and unloading funds have their own fees depending on a method used.

Payments inside the system are instant and relatively cheap. Different withdraw methods and they have their own debit atm card for those wanting it, merchant API available.

Thumbs up TH!
