Displaying pop-up summaries on hover in visualforce

What if I want to make a summary pop-up window when a user hovers over a link in a visualforce page. This Feature is easy in standard salesforce pages, mostly because it happens automatically. But not in visualforce pages. I have seen most of example for pop-up in salesforce were created using the output panels with some embedded styles. 

Here I'm posting a pop-up example which show the details of a partuclar record on a mouseover using the Hover links similar to those used in standard Salesforce links. 

/*visualforce page*/

<apex:page controller="PopupTest">
<apex:form >
    <apex:repeat value="{!accounts}" var="acc">                            
          <br/>  <a href="/{!acc.Id}" id="{!acc.Id}" onblur="LookupHoverDetail.getHover('{!acc.Id}').hide();" onfocus="LookupHoverDetail.getHover('{!acc.Id}', '/{!acc.Id}/m?retURL=%2F{!acc.Id}&isAjaxRequest=1').show();" onmouseout="LookupHoverDetail.getHover('{!acc.Id}').hide();" onmouseover="LookupHoverDetail.getHover('{!acc.Id}', '/{!acc.Id}/m?retURL=%2F{!acc.Id}&isAjaxRequest=1').show();">{!acc.Name}</a>
    </apex:repeat>
</apex:form>
</apex:page>

/*Controller*/

public with sharing class PopupTest {  
    public List getAccounts()
    {
        List accounttList = new List();
        accounttList = [Select Id, Name from Account LIMIT 10];
        return accounttList ;
    }

}

None of which are considered to be supported "APIs" and can change with any major or minor (patch) release without notice. Therefore promote this idea on ideaExchange in salesforce.
