creating multiple views that show in separate tabs of the same block

i'm looking to create a block that displays a different view on each tab. can someone please help me?

specifically,
i'm creating a block that has three tabs. the most commented articles on the site on one tab, the most viewed articles on another tab, and the most emailed is on a third tab.
the key here is that the three views (ie tabs) are independent of each other. i need to apply different filters to each tab. showing the same fields is ok, but i really do need to have different filters on each of the tabs. I also need to be able to display text of my choosing on each tab (viewed, commented, emailed).

i've tried using the views tabs module (among others) and have not been able to accomplish this. i simply get the ability to sort and group by one tab or another. i can apply several blocks but i can't get them to join into a set of tabbed views.

does any know of any modules that could accomplish this? or if it can be done with the views tabs module? or even any pointers in the right direction?

Thanks a million

To anyone who may have the same needs as me:

I found a module that accomplishes the required functionality. the module is called "Tabbed Block" that allows you to create "tabbed blocks" in which a different block view can be assigned to different tabs.

The tabbed blocks can be created in Administer -> Site configuration -> Tabbed Block settings

Even better solution:

use the QuickTabs module

when browsing the issues list (b/c the zen tabs don't work in the zen theme) i came across this. For some truly kick a** tabs, check this out:

hope this helps somebody :)
