<p>Ok, I'm using the term "Progressive Enhancement" kind of loosely here but basically I have a Flash-based website that supports deep linking and loads content dynamically - what I'd like to do is provide alternate content (text) for those either not having Flash and for search engine bots. So, for a user with flash they would navigate to:</p>

<pre><code>http://www.samplesite.com/#specific_page
</code></pre>

<p>and they would see a flash site that would navigate to the "<code>specific_page</code>."  Those without flash would see the "<code>specific_page</code>" rendered in text in the alternative content section.</p>

<p>Basically, I would use php/mysql to create a backend to handle all of this since the swf is also using dynamic data. The question is, does something out there that does this already exist?</p>

Looking at the solutions you linked... it is actually as simple as my frivolous comment!
Here's a version of the Zach Leatherman code that prepends "In " for future dates for you. As you can see, the changes are very minor.
```
```
function humane_date(date_str){
      var time_formats = [
          [60, 'Just Now'],
          [90, '1 Minute'], // 60*1.5
          [3600, 'Minutes', 60], // 60*60, 60
          [5400, '1 Hour'], // 60*60*1.5
          [86400, 'Hours', 3600], // 60*60*24, 60*60
          [129600, '1 Day'], // 60*60*24*1.5
          [604800, 'Days', 86400], // 60*60*24*7, 60*60*24
          [907200, '1 Week'], // 60*60*24*7*1.5
          [2628000, 'Weeks', 604800], // 60*60*24*(365/12), 60*60*24*7
          [3942000, '1 Month'], // 60*60*24*(365/12)*1.5
          [31536000, 'Months', 2628000], // 60*60*24*365, 60*60*24*(365/12)
          [47304000, '1 Year'], // 60*60*24*365*1.5
          [3153600000, 'Years', 31536000], // 60*60*24*365*100, 60*60*24*365
          [4730400000, '1 Century'], // 60*60*24*365*100*1.5
      ];

      var time = ('' + date_str).replace(/-/g,"/").replace(/[TZ]/g," "),
          dt = new Date,
          seconds = ((dt - new Date(time) + (dt.getTimezoneOffset() * 60000)) / 1000),
          token = ' Ago',
          prepend = '',
          i = 0,
          format;

      if (seconds < 0) {
          seconds = Math.abs(seconds);
          token = '';
          prepend = 'In ';
      }

      while (format = time_formats[i++]) {
          if (seconds < format[0]) {
              if (format.length == 2) {
                  return (i>1?prepend:'') + format[1] + (i > 1 ? token : ''); // Conditional so we don't return Just Now Ago
              } else {
                  return prepend + Math.round(seconds / format[2]) + ' ' + format[1] + (i > 1 ? token : '');
              }
          }
      }

      // overflow for centuries
      if(seconds > 4730400000)
          return Math.round(seconds / 4730400000) + ' Centuries' + token;

      return date_str;
  };
```
