Check out Facebook's FlashCache: they use SSDs as a cache on to traditional HDDs. You can have a read-cache to keep 'hot' data fast, and (if you want to) you can have a write cache that will buffer writes on SSD before flushing to HDD.
I don't know whether it's ready for general (non-Facebook) use yet, but it is definitely one to watch.
My strategy from now on is to to mirror the SSD to a traditional HDD. That way, in the case of a SSD failure, we can accept the performance hit and still be able to run smoothly from the platter.
