I'm on a roll today.
If you've ever used Apple's Safari and enabled the debug menu there's a submenu there that allows you to view the current page in another browser (Opera, Netscape, Internet Explorer or Mozilla Firebird). What's lacking is my default browser: iCab
Here's an Applescript you can put in your Libary/Scripts folder to view the current page in iCab:
tell application "Safari"
set this_URL to the URL of document 1
tell application "iCab"
Paste the above into a new Applescript document and save as a normal script (no need to save as an application or whatever). Now you can easily access this script from the script menu
