I'll explain this at some point:
    package require tcom
    wm overrideredirect . on
    pack [canvas .c -background blue -height 20 -width 20]

    proc paste_on_top_IE toplevel {
        set application [::tcom::ref getactiveobject \
                             InternetExplorer.Application]
        wm geometry . +[$application Left]+[$application Top]
        raise .
        update idletasks
        after 300 [list paste_on_top_IE $toplevel]
    }

    paste_on_top_IE .


Notice the use made of [tcom].

Intermediate-level browsing:  communication with an existing browser
instance, as opposed to [invoking browsers]:  under Unix, netscape
recognizes a -remote flag, to try to re-use an existing browser 
process.  Also, Netscape (and other browsers) respond to a few
[DDE] commands, and 
http://www.neosoft.com/tcl/ftparchive/sorted/net/netscape-remote-v1.2/
is a Unix(-only?) extension for communication with Netscape.

[Ro]: Communicating with netscape on unix without -remote flag [http://groups.google.com/groups?dq=&hl=en&lr=&ie=UTF-8&safe=off&selm=m3n0sbfuc0.fsf%40nova.revier.com]:

''Yes, it does, eventually. There is a Tcl-extension that does the same thing (communicating with Netscape using X Window Properties) without starting another instance of Netscape, which works much faster (almost instantly and without any overhead). I haven't tried it with recent versions of Tcl/Tk, though.''
