Masked input plugin with date limit

Question

I am using masked input in an input text box for a date in MM / YYYY format. ( http://digitalbush.com/projects/masked-input-plugin/ )

My javascript code is:

jQuery(function($){
   $(".date").mask("12/2099");
});

And the HTML code:

<input type="text" class="date">

When I start to write something, it takes the value 12/2099 in the field, and it is impossible to write another thing.

If I write 99/9999 in a javascript mask, users can write a date, which is a lie ... so I'm not doing what I need to do?

I want users to be able to write from 01/1990 to 12/2099, perhaps adding to the restriction with a date value of + 20 years or something like that ...
