PVLAN are great for this purpose, just keep in mind that they area acting as L2..so if you are using SVI then you need ACL on top of PVLAN.

Re: How to Block communication between two same vlan

Depends on you switch model and IOS installed, you can use PVLAN as mentioned by Colin.

Here is the matrix of switches and IOS that supports PVLAN http://www.cisco.com/en/US/products/hw/switches/ps708/products_tech_note09186a0080094830.shtml

You can also use Vlan access-lists (VACL).

If you checked Danilo's link, you will notice that the 2900XL/3500XL cannot support PVLAN.

2900XL/3500XL also cannot support VACL.

Hope this helps.
