The version messages exchanged between peers right after connecting contains the current block height. You could take the median of your peers' heights as a low-reliability number.
Thanks. Low-reliability is not an issue, as it is an indication for visual purposes.

No.
I'd like to show a progress bar on initial download on the block chain, or when the client was disconnected for a while and needs to catch up.
This would give the user a more useful indication than just a raw count.
There is nBestHeight (which can be queried with getblockcount/getblocknumber), and the IsInitialBlockDownload function, but those only take into account the downloaded blocks. Is there a way to find out how many blocks there are in total? (without querying a third party)
