We've discussed this quite a bit on the Guild of Accessible Web Designers' list. The consensus is that we don't buy this "it's an early version" reason for being so thoroughly unusable by people with disabilities. It's easy to say "it's only a beta version" to abdicate responsibilities. How long has it been since gmail became available? 4, 5 years or so? And it's still in beta!

The thing is, as long as accessibility is an afterthought, we'll see people unable to use things. And then we are told that the reason more of an effort isn't made to include accessibility is that people with disabilities don't use the product! Bit like Pete, my car mechanic back in Chicago. I told him he should put a ramp to his office. He asked "why should I put a ramp to my office, you're the only guy in a wheelchair that uses my services". I asked something like "why do you think that is?". Pete was an excellent mechanic, honest, quick, affordable. A gem. But as long as people couldn't get in, they were unlikely to go. He put in a ramp, and within a month had 12 more regular customers. It's a bit like that with software too.

As for turn up and help coding it, I would if I had the knowledge and time.

Cheers :)
