I have created an activity wall using a custom data template. Still bit rough, should work as an example.

Limitations:
- EXTJS row highlight looks odd if a user clicks into a row
- This exmaple does not have any links,, but you can use AwareApp links.
- User must double click to perform the default operation.
put this into a css file, or the header of the custom layout.
<style>
.vsg-wall-div{ font-family:'Tahoma'; font-size:11px;}
.vsg-wall-status{ font-size:30px; vertical-align:middle;}
.vsg-wall-title{font-weight:bold;}
.vsg-wall-desc{ font-size:11px; max-height::30px; overflow:auto;}
.vsg-wall-datetime {font-size:11px; color:#cococo; }
.vsg-wall-highlight{
color:#1986b5;
font-family:'Tahoma';
text-shadow: 0 1px 0 #fcfcfc;
text-align:lef;
margin-bottom:15px; }
.vsg-wall-tools{color:#1986b5;font-size:11px;}
</style>
this is the body...
<div class="aw-data-item">
<div class="aw-custom-line">
<div class="vsg-wall-div">
<table cellpadding="2" border="0" width="100%">
<tr><!-- Row 1 -->

<td valign="top" ><span class="vsg-wall-highlight">{Owner}</span> Updated a <span class="vsg-wall-highlight">{ObjectType}</span></td><!-- Col 2 -->
<td valign="center" align="right" rowspan="3"><span class="vsg-wall-status">{Status}%</span></td><!-- Col 3 -->
