I was sick of waiting 24hours for blockchains to download so I have uploaded one for all to download.

Blockchain is available here:

Just download and copy files into datadir.

Is it a security risk?
No. Just so long as you let the rest of the blockchain download on top of it. Would be impossible to create a blockchain that was fake that could have real blocks linked on top of it. Just check that the number of blocks in the client matches the number here http://blockexplorer.com/q/getblockcount .

If service is well used will update daily.

Sorry file is very large so can not host for free - downloader pays if they want a high speed download - but you can pay in bitcoins!
