You could still do identity verification using either a 3rd party service, or by getting sight of ID documentation. (Certified copies of passports posted out, for instance. Sounds mad, I know, but I worked at a gaming start up and we had to do that for some customers!)

In fact, you'll have to do that ANYWAY to be compliant, regardless of the method you use to fund accounts.

True, although by the time you've signed up and proven ID, you've lost the 'spontaneous' appeal of the site (making it quick and easy to have a bet). I guess the site still has the advantage of low-cost money transfers and no risk of chargebacks, so bitcoins may have a use here.

I wonder if it is possible to use bitcoins and comply with the UK gambling restrictions against money laundering? At first glance, it looks impossible, bitcoins being (supposedly) untraceable. However, you might be able to comply if you insist that winnings are always paid back to the same bitcoin wallet that they came from. The justification here being that your website won't have 'washed' the money any further than it was already laundered.

Limiting the 'spontaneous' gambling is part of what you have to do to comply with Gaming Commission rules - you have to include ways to limit the amount of money deposited or gambled, and you have to provide a mechanism to self-exclude, or ban yourself from playing.

I'm more interested to see if these guys get shut down or if the Gaming Commission would turn a blind eye. I notice no available contact details on the site or domain name registration. (Good for avoiding the law, bad for making me trust you with my money.)
