It is possible to go even faster. The fastest rate is something like that, if you assume the time in the Genesis Block is zero: 0 1 2 2 3 3 3 3 4 4 4 4 4 4 5 5 5 5 5 5 6 ... Then you can increment timestamps once per 6 blocks, that means x3600 increase, but then the difficulty is always multiplied by four, so you have to increase time once per difficulty change to keep it on real level, then it will wave between being multiplied by 4 and by 0.25.

This just kicks the can since that then imposes a limit on the maximum number of blocks, but at least the unit is now ~10 minutes instead of 1 second, a massive x600 increase in the amount of time we are forced to hardfork. On the other hand, this does imply that the difficulty calculation will become astronomically and ludicrously high, since pre-softfork nodes will think that blocks are arriving at the rate of 1 per second, so ...
