You probably want:

    open "`echo $TM_FILEPATH | sed "s|.*/$USER/Desktop/\(.*\)|http:// 
localhost/~$USER/desktop/\1|"`"

Which makes a file path of e.g. /Users/duff/Desktop/test.html into  
http://localhost/~duff/desktop/test.html

You can also use the shells ability to chop off a prefix ($HOME  
points to your home folder), e.g.:
    open "http://localhost/~$USER${TM_FILEPATH#$HOME}"

If you do spell Desktop in different case (lowercase for the URL):
    open "http://localhost/~$USER/desktop${TM_FILEPATH#$HOME/Desktop}"

Btw: instead of opening the URL, you can also set the commands output  
to HTML and then let it redirect to the URL, so you'll view the page  
inside TextMate:
    echo "<meta http-equiv='Refresh' content='0;URL=http://localhost/~ 
$USER${TM_FILEPATH#$HOME}'>"

I recently blogged about both shell variable substitutions and HTML  
output capabilities:
