Excel 2010 password protection


I have built an app in Excel 2010 and want to distribute it to clients ao that they can't see the VBA code etc. I know that Excel could be cracked by a host of software until 2007.
What options are available to protect my code in 2010?

To protect your VBA code:
When in the VBEditor, right click the workbook name, select ProjectProperties/Protection, add the check mark and enter the password twice, press OK. That is hardish to crack and few people will even attempt it.

Also suggest distributing as a .xla or .xlam add-in (with the protection patrickab suggested), if it make sense (e.g., it is an app and not a spreadsheet for data entry, etc...)
