I noticed this in the logs on one of my sites this morning...
IP: 22.214.171.124 UA: Scooter/3.3Y!CrawlX
Requested robots.txt and the index page.
Not sure if anyone has mentioned this UA yet.

I've also seen it crawling this morning, same IP and UA.

Since AltaVista was purchased by Overture the A/V engine often uses the listings in Yahoo. Lookup of IP 126.96.36.199 which is often used for the UA of Scooter/3.3Y!CrawlX reveals that the IP "does" belong to Yahoo in San Jose, CA, USA
Having noticed comment by others that they have been blocking this UA, thought I should pass this info on as it does seem valid as a good bot.
