I've got remote debugging going at one of our clients and all I can say is WOW!
For some reason remote debugging had a bad rep in the back of my mind. And although installing it wasn't very easy due to firewalls and cryptic error messages, once it worked I fixed 5 bugs in 5 minutes. They were bugs related to timming issues with the SQL Server, they only happended at the clients enviroment because their server is optimissed for this application and our development server runs some other things as well.
My project manager now logs in using VPN/Remote desktop and breaks the application while I am connected with the debugger in a different VPN/Remote desktop session. Instead of having to reproduce the bugs at our end after a "vague" description of the steps to follow I can see what happens instantly, it's just pure *bliss*
I want to thank Gregg Miskelly for his help on diagnossing why the remote debugger didn't work initially, check his
blog for allot of usefull information about remote debugging
