Are there any clients that support 0 BTC transactions?

No. This is to prevent DoS attacks on the network. Each transaction must include a fee.

Transactions are not required to include a fee. Zero fee transactions are fine, and will make it into blocks rather quickly if they have a sufficiently high priority (input age).

The DoS prevention measures are enacted by the enforcing the dust limit (min transaction relay fee), based on the cost to the network to spend the coins.

Is one satoshi (0.00000001 BTC) close enough?

Sure. Is that widely supported?

Doesn't seem like it's widely supported, but if you can find a miner willing to include a one-satoshi transaction (or be that miner), it's possible: https://bitcointalk.org/index.php?topic=516276.0
