Export spread sheet option in MOSS 2007

Hi all,
Last week i had a small requirement in my project, where i need to enable "Export spread sheet" to Sharepoint Viewers group(Usually users in Viewers group will not have access to use "Export to spread sheet" option) of the sharepoint site.
To accomplish this, I have decided to create a simple web part page where in i will drag and drop the list in the web part page and add another Content Editor Web part.
Now, Modify the content editor webpart to create the html link with the following url.

http://servername/Sitename/([Subsitename]/)_vti_bin/owssvr.dll?CS=109&Using=_layouts/query.iqy&List=[ListGUID]&View=[ViewGUID]&CacheControl=1

Save the changes, your job is done :-)
