The best solution there would be using some sort of web based hosted solution, which may well not exist. Thinking something like how TT-RSS replaced Google Reader. Basically, self hosted Google Groups, back when Google Groups was synonymous with web based usenet. Shouldn't be too crazy to cobble together, if it doesn't already exist -- just an nntp client on top of a lamp stack.
