If significant demand appears among customers for bitcoin support, we will look into adding it. However, it would likely come after Google and Amazon payment support, and I have serious reservations about the idea, as the anonymous nature of bitcoins would not be a benefit; being one of very few hosters to support it would paint a bullseye on our back for spammers, scammers, and anyone who we want to stay banned.
By all means, you should avoid Paypal.
Seems sensible, you will indeed see more revenue on Google and Amazon.
With regards to the anonymous nature. Bitcoin users are in no position to be able to scam you (ie fraudulently obtain services) as, once the money is in your wallet, they can't take it back. There is no way to reverse a bitcoin transaction once it is confirmed. It's certainly more safe than credit cards and paypal, which can both have chargebacks.
If your talking about people signing up anonymously and using the servers for nefarious things, I can see the concern, that said, it's not that difficult to be anonymous using other currencies either, prepaid credit cards, signing up for paypal with false information, or plain old identity theft are just a few ways of doing it. If it became an issue, I'd suggest requiring some form of identity validation.
