Well, I received today a notice that the xRM Challenge is two days from wrapping up. There are a significant number of entries from all over the spectrum, each powerful and useful in its own right. The top contenders have very large numbers of votes, and all practically upend the out-of-box functionality of CRM to meet purpose-driven goals.
On a side note, I feel that my project would probably fare better in a challenge that promoted projects which benefit the CRM Community. This challenge seems more like a free advertisement venue for proprietary products with small numbers of beneficiaries.
