Toast is currently creating a new genesis block with the sharedropped balances:

To answer your questions:
> 1. Are the Key ID Bitshare DNS developers in the process of sending BTS to BTER and other trading exchanges?
Nobody will "send" any DNS anywhere. Instead, there will be a new release of the BTS client that includes the aforementioned sharedrop genesis block.
> 2. Why has there been a long delay before sending BTS to BTER et al?
Preparing aforementioned genesis block takes some time.
> 3. When is it expected that the devs will send BTS to BTER?
AFAIK there hasn't been a release date announced yet. I'd expect this to happen within the next two weeks or so, but that's just a wild guess.
> 4. If the DNS is now worthless and the devs are unlikely to send BTS to BTER (based on the snapshot) is my investment worthless? Did I buy magic beans (I make no particular complaint as I knew it was high risk but I would like to establish the facts from the jedis here present).
DNS are now worthless because the KeyID chain has been stopped. It has been stopped because of the sharedrop.
Your investment is not worthless, though, because the devs are *not* unlikely to "send" BTS to BTER. The fact that you owned DNS at the time of the snapshot entitles you to some of the sharedropped BTS.
