Hey, it's been a loooooong time since I was on here, I'm really glad to see DonationCoder is still around!

I often have clients who change their hosting services for web or email, and a lot hinges around knowing when their domain has propagated over to the new IP address. I envision a utility that I can put one or more hostnames in, and flag their resolved IPs as the "old" hosting server, and set an email address to notify when the IP changes (ie. the domain is now pointing to the new host). You could set an interval on which to perform the domain check, eg. every 1, 5, 10, 60 minutes, 6 hours, daily or however would work best.

If such a tool already exists, I've never encountered it before.

This would be a very handy utility for sharing full info on collections of files between friends. I could create a ZIP or RAR file which would be a browseable copy of the folder tree, except each of the filenames stored in it would be zero bytes in size, so my friends could immediately see all the files I have and plan what to copy from me the next time come over for a visit.

Anyone keen to help out on this one?

All great suggestions, I guess there's not a need for an app to do this after all :)

Thanks a ton.
