Did you know that Microsoft ESP is now part of MSDN? As a result of months of hard work by the good people at ACES (yes, Todd, that includes you too! :-)) you can now find the ESP developer center on MSDN. If you're an MSDN customer, you can also download ESP without having to go through the normal purchasing channels.
Let me know if you need assistance with developing on ESP! Also, if you are a current or potential ESP customer and require contract work or help with developing your software, I'd be interested in hearing about it as well!
Here's the link for where all that good fun happens!
