Sorry macguba - I don't know Petroizkis address, and I haven't seen him on the new forums,or for quite a while before the old forums closed. I'm also not sure how he would feel about these scripts being hosted as he was always quite insistant that these were only betas, and there was better to come (in fact I'm not even sure if the versions I've posted were the final version he posted).
I guess you could host them without permission, then if the author appears and objects you can take them down. Alternatively myself or another scripter could have a bash at updating the scripts, with due credit given of course. Looking through the scripts I can see there are lots of features that Petroizki had planned, but hadn't implemented.
Either way these really do deserve a place in the editors depo - they add so much character to missions.
[edit]Just checked the members list and found Petroizki is registered. Unfortunately his e-mail is hidden, and he hasn't posted in the new forums.[/edit]
