Subject: POS#1 Self-Executing HTML: Internet Explore
	 r  5.5 and6.0 Part III

I think this was discussed earlier also in full-disclosure, using
ADODB.stream object. 

http://www.mail-archive.com/full-disclosure@lists.netsys.com/msg06791.html

Also, Quick serach on google found this

HOWTO: Use the ADODB.Stream Object to Send Binary Files to the Browser
through ASP

in this code, the actual exe is contain in javascript array named
'jelmersArray'. it is converted to string by tostring function.
