Hi Ken,
There have been java applets that did this with the user's consent, e.g.
the MD5crack distributed computing effort had one:
http://distributedcomputing.info/recent.html ,
http://www.engsoc.org/~jlcooke/
It is not inconceivable one could do something useful with
ecma/java/j-script too, however it would have to be some variant of AJAX
to be useful to whomever wrote/hosted the script?
However, I don't think you're likely to see anyone stealing your CPU
time with this as of yet.
Maybe someone else has different thoughts on the matter :)
- Jeroen.
