I think this approach definitely has merits. At the company I'm currently working for I've pioneered the use of Perl, so before Perl got "generally accepted" (this took about a year) my colleagues didn't use the software I wrote "because it was too much trouble to install" (not too difficult, mind you, too much trouble: modules and what not).

Life would have been much easier with a tool to bundle software à la PAR or a PRE as suggested in this meditation. At some point a -- gasp -- Visual Basic program was used rather than my Perl code since the latter was a simple executable and the Perl version required installing a few modules.

To conclude: I second this suggestion whole heartedly.

Just my 2 cents, -gjb-

Update: my thanks to grinder for suggesting the correct HTML entity for à.
